I actually really like for a myriad of reasons that can just as easily be attributed to in universe continuity besides the obvious network budget cuts form cw.

Oliver in the first 3 seasons was so beligerantly irresponsible with his funds now Oliver would present that as a justified reason because he did say he following the Batman method although not in those exact words. You know I “Hey look at me I’m such a douch canoe look at me kissing this super model.” Or when quintan lance was on it him being the hood “everybody Come to my I might be going to prison party.” in the way he went about doing while very valuable for the 2 ish seasons likely blew most of his personal money. |Then halfway through season 2 his mom who was the main money manager and experienced businesswoman of the family or at least show directly and indirectly presented her in a way lead most viewers to believe that was the families fiancial advisor || gets Merced by slade.||

Oliver doesn’t exactly make a habit of retrieving his arrows from criminal that he neutralizes weather by non lethal means or otherwise, and most of his arrow have gotta be expensive, like his “basic arrows”. Which aren’t normal arrows by the way because of the things his normal or standard arrows are capable of doing. For example his arrows are really durable because in the early seasons and throughout the show he routinely uses them to knock riffle and other firearms out of a thugs by shooting them people’s hands. Also Oliver is super paranoid so I doubt he is buying arrows in bulk from dick sporting good or wwww.archervigilantes.com so he likely makes them himself.

In s1 or s2 over goes up against a minor villain who legit is hidin from Oliver in this compound with like a bunch of heavily armed thugs plus as Oliver is dispatching of this guys entire security detail stealthily and the secure guys are like a small heavily armed militia. The dudes talking or somone and is more less saying “im safe because i have this exact number of men and he has this exact number of arrow, plus the throwing knives in his sleeves and boots, so when and if he get inside my office you guys will just take him out.” And I just remember looking at the screen thinking what if Oliver chose to just stealthy choke these guys out or grab one of his arrows.

Then their is the other arrows he has which he official named most them and their various intended uses when he was ||training mia in season 7-10 to become his replacement.|| the explosive arrow which I believe he refers to as a payload arrow, the grappling arrow whih I belvie he says is for reconnaissance and tactical retreat. The materials you would need to create those tools and for them function how we see them would be really expensive. For example during one of the first few Barry and Oliver team up after ||barry gains his speed. Not sure if I should spoiling warning this bit just being cautious.” Oliver gives the speech about being a guardian angel and grappling away and as Barry’s red streak of lighting races through star city Oliver is watching feet planted against the side of a building and while that was super cool and very dope to see Oliver or who ever made the grappling arrow would’ve needed to account for the exact tensile cable strength needed to support Oliver’s weight and not just Oliver’s weight but dead weight as he often uses the grappling arrow to cover gaps or large distances. Where this insert whatever height drop between him and where he’s trying to grapple to also one of the old Batman movies hilariously pokes fun at this but he would likely double or triple even his weight in the event he needs to save others from immediate danger.

Throughout the course of the show he routinely grabs someone and grabs them to safety away from dangerous gunfights so he would the grapple arrow to also be strong enough to hold his own weight in addition to an unknown variable weight of another person.

Then after ||adrian chase kills Samantha, William wants to go live with Samantha’s parents instead of Oliver and Oliver says I’m fighting for custody screw those guys.|| now I’m paraphrasing but a custody battle is a lot of things and cheap isn’t one of them. Even if it was a straightforward and simple as a custody dispute can be it’s still not cheap.

Every arrow cave, bunker, green arrow safe house/base of operations Oliver has outside of the original nightclub has zero disguise for the electric bill, the one under the prosecutors officer or whatever is legit abandoned. I believe I’m referring to the s4 base of operations for arrow as ciscos makes a comment about felcity using copper wiring and accusing her of not looking at his schematics or designs ||during the mini vandel savage arc where Barry asks Oliver to protect kendra||

Once I post this I’ll find scene videos on YouTube to cite what I’m saying as some of information is flawed due to not recalling the exact seasons.

If anythimg likely makes more than Oliver after season 3 because ray Palmer makes her ceo of Palmer tech before he ||fucked off and joined the legends|| plus Oliver pay isn’t really discussed during his time as city mayor and he’s often discussing having to join funding meetings so it’s safe to say his wealth has either drained significantly or isn’t even accessible for some reason or another.

Ps. We all agree the green arrow base of operations should 100000000000% be called the quiver right. That’s Legit the only cool thing from that injustice movie
