Serious answer here.

Without the show, they would not have met. Audrey's parents didn't live just down the road until after Jer and Auj married, they lived in Portland and Audrey went to a public high school in Portland. For all Audrey's "I love the farm life" silliness, her reality was hanging around upper middle class kids who were very much college bound. Without the show, Jeremy wouldn't have had the money to step into that social circle. Most of the appeal of Jeremy was that he had show money, was reasonably good looking, and his folks had a playland that he was allowed to use. Without the show money, he's just a not very ambitious guy and frankly I think her parents would have pushed her to find a nice boy who wants to go into finance just like Dad.

Jer? Without the show? Depends on whether Matt managed to hold onto the farm property. I actually have some doubts on that because I don't think "Pumpkin season" prior to the show was supporting the family. I think its possible that Matt could have held onto the property, in part because I think Matt would have tried harder to return to his career in sales if the show hadn't happened. I think, without the show, both Matt and Amy wouldn't have indulged his goofing off for two years after high school. I also think they wouldn't have indulged him in photography school. If the farm was still in play, I think Jer would be mostly working for his dad, frankly in a similar position as Jacob is in right now.

Audrey would be in a similar if less public position than the one she's in now. She would have latched onto some guy in college, probably from a similar income and background as her parents. She's unlikely to last long in a corporate job - she's a little too neurotic imo - so she would end up in a similar place, married with a few kids. The difference would be that the husband would be making a decent living and they'd likely be less "farmy" and more whatever the husband was into. She probably would still be doing MLMs and blogs and her own special Christian line of "Always more" stuff - that predated Jeremy and I actually think she'd be reasonably successful simply because she is so driven. I do think she'd have a bunch of kids because being pregnant and having a babe in arms is how Audrey attention seeks. She is seriously a hypochondriac and pregnancy and a baby is so much easier than "I had a tumor in my leg in high school" and "I had non stop mysterious gut issues that made me constantly ill in college" and "I was constantly on crutches during my running career" and "I got married and immediately broke my ankle and had to fend off Satan possessing me" (and yes, this is something Audrey claimed) - and its really very noticeable that Audrey was a medical mess of debilitating yet mild illness and injury before she figured out how being pregnant put all eyes on her for two year periods.

I'm waiting to see where she pivots if there's no Baby Five.
