OP has valid feelings here. They are noticing how our modern world is an intermediary in social relations. How removed we are from nature, and social connections. How social connections were key to survival. Etc.

At the same time, I think it's potentially dangerous to come to this conclusion through the filter of media. Media can be thought-provoking and cathartic, but it shouldn't act as a substitution of reality.

The modern world has problems for sure, but the idea that things were better "back in the day," artificially instilled by the media we consume, veers uncomfortably close to the same type of mindset that allows regressive political movements like MAGA to take off.

OP has valid feelings and I doubt anyone is dismissing their feelings. What most people here are dismissing is the conclusion OP came to about their feelings, which is:

I’d rather die trying to hunt for food and learning how to survive in the woods

If the people here were a genie and granted OP their wish and sent them back into the late 20th century, they'd be dead in a week. They have very much romanticized themselves a setting that is a fairy tale and they now want that fairy tale. But the reality is that the 20th century, especially the kind Arthur Morgan lives in the game, is far from a fairy tale. I'm not OP but if I had to choose between living in the 20th century America or live in the right here and now, I'd choose here and now every single time. I've camped out in the woods, I've grown my own food, I've foraged for food. I've rolled around in mud and washed myself in a river. I wouldn't want to do those things (and a 100 other things I've never even done) for the rest of my life. I'd rather have the comfort of my home and spend the weekends doing those things when I feel like it.

OP has valid feelings but it doesn't mean they should reject the modern world. If they want to do that they can start doing that gradually. Learning how to cook meals from whatever they have in their cupboard. Learn how to camp in camping spots. Learn how to tend a garden. Learn how to forage. Learn a 100 other things and when you know how to be self-sufficient and you still feel like the urban space is pushing you down, sell your shit and buy a home in the middle of nowhere and live off the land or whatever. Just learn to be self-sufficient before you reject modernness, because the lives we live don't really require us to survive on our skills. I imagine most people don't even know how to cook a delicious meal because it's far more convenient to have it brought to your doorstep. And cooking is the most basic skill you should know.
