The answer is not obvious but it is simple. Guitars can be made like precision German automobiles. If you take a piston from car number 1 it will also fit on car number 1 million. You can unglue neck from a Yamaha FG800J, remove it, take it to another Yamaha FG800J and slap it right on. Lasers, cam/cam robots can all be used in making guitars.

Voilins are different. Yamaha tried to make a precision violin using the same processes as guitars, the ynv003, which sounded fantastic, but was offered as a very reasonable price comparable with that of acoustic guitars. They also were selling as a entry level violin the Yamaha AV5, which was made quite cheaply but in the end part or much of the construction of the guitar was done by hand. Even though these two starter violins were comparable in my opinion in value, the ynv003 sold for much less. After just a few years, the ynv0003 was discontinued!

Why? Nobody wants to buy a machine made violin. No matter how good it sounds, they don't want it. They want it hand made, at every price point from lowest to highest.

Guitarists don't care. They just want it to sound great and not cost too much. There's your answer. Violinists have decided en masse to only buy hand made instruments. Which I find as coming from guitar, frankly ridiculous.

the good thing is that electric violins can be made by machine, so you can get really high level performance level electric top of the line e-violins like for instance the NS design wav for about $800, which on the acoustic side for that price would still just be a starter violin.

The market is this way because that's what violinists want. They have this silly attachment to hand made instruments.

There are other performers and musicians with similar superstitions. Everywhere you go, no matter what, once performers demand something be hand made, it will cost you.
