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.
Worse than that, some jurisdictions double-dip: regulate internet access like a utility, but treat it as a private resource (allowing regional monopolies that provide barely-usable service and set their own prices); 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).
