If people lived next door to just these non-industrialized private farm, then they would eventually become Vegan.

Heh, I've seen this said sooooo many times, but I feel like the opposite is true. I grew up in a small village, a few hundred people. We didn't have a farm ourselves but many of my friends did, so I hung out around them a lot.

I don't claim to know everything about the conditions because of that, but I did see someone put their arm inside a cow and horse and my grandma once showed me how to slaughter a rabbit (we ate it later), so it's not like I was sheltered from the more graphic aspects.

Yet, when I look back at the people in my life (and I'm quite old and moved around a lot), all the vegans I know are city people. I'm really not aware of any vegans from my home area, which is much more rural. Being around animals in a farm setting doesn't seem to make people vegan, it desensitises them, at least in my experience.

For context: I'm talking about a rural area in southern Germany, I'm can't really say how things are in other regions.
