Sure, if you don't mind living out in the sticks :P France has a big concentration of people around the big cities with a big empty diagonal in the middle of the country, form south-west to north-east (literally called 'la diagonale du vide'). Not only are you far from anything resembling a city, but infra for public & private transport are lacking. So if you can wfh and find a place with good 4g/5g coverage, and you won't miss social interactions, it can be great value. But as soon as you get closer to e.g. Paris or Lyon, things look very different.

Sounds about perfect where do I sign up.

There are lots of websites where you can search for rural housing in france, but it's quite fragmented so there is no real one-stop-shop where you can find everything. You can start here though: https://www.proprietes-rurales.com/ (I am not affiliated in any way with the website, was just the first one i found)

You won't "live for free" as France has quite a high tax rate. But if you have any valuable skill and are open to the culture you can certainly live a good life there.

I just meant rent free obviously.
