Just to be clear: everything in nature also has a ROI of sorts. I would say people who live in nature are also constrained by their environment and have to be very economical. They depend on their tribe, on the cycle of seasons and the weather, have to be prepared for chance meetings with predators, can't fully prepare for other things like trauma, infection and natural disaster etc.

The closest you can currently get to "doing as you feel", involves moving to Europe and becoming dependent on the socialist state. You can live for free in a flat forever, never have to work, get free health care for every booboo, just hang out all day surrounded by people who do the same thing. I would say this is currently the state of the art in living an unnatural life. And as a result, you might end up being miserable.

But I do sort of understand what you mean; our brains were built for living in natural environments. These impose fairly random and complex constraints, with stress coming in big but short-lived peaks and real family being constantly around.

Living in a concrete jungle and having constant low level stress, doing and eating the exact same things every day, taking pills for every little ill is a recipe for alienation and early death.

Your view of the welfare state seems extremely skewed. One can certainly not just move here and profit.

Well not sure what country you're in. I did live in the middle of it for many years. This is just my personal impression of the system.

But I don't intend for this to become a political discussion. To me, this is just an effective example of how "doing what you feel like" can be very different from living in nature or in a natural state and being happy.
