You might be surprised just how many homes run on a well and septic system. Day-to-day, walking into my house, you wouldn't even know the difference between my home and one in the city. We also don't need to chop firewood. My completely standard modern furnace runs on gas, just like ones in the city. Admittedly, I need to supply the gas, but that infrastructure is also well-solved. I just need to make sure to order more when my tank is near empty, and a truck shows up and fills my tank. I pay them instead of the utility companies.

What is more likely to throw you off is services like trash. There is no centralized trash service that just picks it up. You need to handle it. Most of the time, people still hire someone to do it, so it also ends up being the same as living in the city, but you need to actively seek out a solution. Or DIY - I know plenty of folks around here who don't mind taking their trash to the dump once a week or so.

And you cannot order food for delivery. That simply does not exist here.

Not that you are wrong that if we had to go back to living like we did hundreds of years ago, it would not be comfy. But the reality of living out in the country is not as different as you seem to imagine.
