The back-to-nature theme is fine for privileged landowning educated people. But the vast majority of everybody everywhere is dependent on the local grocery.
And yes, hypersanity is probably the most extreme form of privilege. Also, the back-to-nature theme is great, not merely fine, and something indigenous cultures are trying to reclaim as a human birthright. They're arguably way less privileged by your standards. Privilege isn't a reason to dismiss a good idea.
Treating nature as something to live with collaboratively rather than avoid or treat as subservient/separate from us isn't privilege. It's science. Mutualism > competition.
Its 'privileged' to preach that nonsense to apartment-dwelling two-shift-working people with barely the time to visit the bodega on the way home.
Its 'privileged' to imagine this approach to live could be for more than indigenous peoples (rapidly dying out, why is that do you think?) and upper-class first-world wealthy dilettantes.
Privilege is there to be shared. This includes privileged wisdom.
Indigenous cultures are dying out due to settlers and colonizers decimating their lands, cultures, and people. This is not news. It has nothing to do with their way of life, aside from not having developed appropriate weapons and immune systems from those who would seek to kill/displace them.
As for the global food problem, I personally hypothesize capitalism needs to fall or radically transform before that can be addressed.
Learning to peacefully and freely share food seems like the simplest way to address current food issues, but people's desire for money seems to get in the way.
Your take is simply a disempowering reason to stay stuck. We can always reconnect with nature in various ways. Your perspective is self-limiting and keeps you from realizing ways to accomplish it.
Other people are probably figuring out how to do it and you haven't even bothered to find out how.
Here's the first link I found from googling "how to reconnect with nature while living in a city." These are decent approaches and I would say are barely scratching the surface.

If you want to reconnect with nature, you can. You sound like you don't want to believe it's possible, but even the smallest amount of effort can make a load of difference. Have you done any googling to challenge your belief? Have you sought out free ways to reconnect with nature?
But I'm hyper-aware of how my situation is utterly different from billions of humans on this planet, with little or no access to even a tree. Or opportunity to sit under it. Living in high-rise apartment blocks far, far from these imagined opportunities.
The world out there is more like blade runner, than a utopia, for the vast majority of people.
The mind is a powerful tool and if people believe they can use it to reconnect, they're much more likely to find a way to. When it comes to subjective experiences, it's important to engage cognitive biases in the direction we want them to go. Beliefs are useful for that, so we need to choose them wisely. Telling people they're not capable of accomplishing things is only helpful if they're rebelling against you because then they'll take it as a challenge. For others who are already in a disempowered state, they could use your message as reinforcing their stuck perspective. I choose to view life in such a way as to promote change and well-being, not get me or anyone else who hears my perspective stuck in it.
