The Romanian model of "micro ISPs," ISPs serving a few blocks here and there, is also illegal in most U.S. cities. The U.S. places a very high value on universal coverage, both of lower-income people and rural people. In nearly any U.S. city, the only way you will get permission to build Internet service to anyone is if you agree to also serve low-income communities or rural parts of town, even if doing so isn't profitable.
I used to live in an apartment building with both cable and fiber. Nobody subscribed to the fiber because the fiber provided didn’t have a franchise to offer television service. It was nuts—I was the first person on a floor of almost a hundred apartments to get the fiber service. I found out because the ONT had been misconfigured when it was first installed years before. People just didn’t care—they wanted their cable package with ESPN. It’s why Google Fiber offers a television package—a broadband only service is not competitive in most US markets.
Now we have 3 major ISPs and they all offer similar services.
The fact I pay 75 dollars for the same service doesn't sound so absurd after accounting for that.
And like consumer electronics, which easily flow across borders, which is why an Xbox costs the same in the USA and Romania, ISP is a local service that relies on local labor costs.

Government-sanctioned monopolies, and regulation to prevent competition from having a fighting chance. Basically regulation in the wrong places, while looking the other way in areas that could actually use more regulation.
