probably worlds colliding
some ppl view "internet service" similar as access to drinking water, which some countries have legal obligations for and the public sentiment would be very much against you if you deny it to any stranger.
some countries/ppl not so much
Worse than that, some jurisdictions double-dip: regulate internet access like a utility, but treat it as a private resource (allowing regional monopolies of barely-usable service); make an internet connection legally mandatory (via a combination of employment, banking, and anti-homeless laws), but decline to fund public libraries (which provide internet access to those who otherwise don't have it).
No, I don't think I will. I will continue to keep my wifi password protected so that randoms can't degrade my Internet speed by torrenting movies 24/7, send death threats to public officials from my IP address, or engage in other unsavory activities.
Not sure why you are equating a natural resource like air with a paid service like Internet connectivity, but it comes off as bizarre and naive at best.
