>The government at every level, should have no power to prohibit entities, whether government or not, from providing internet service.

Sure they should. You're being ridiculous.

The first amendment doesn't mean anyone can do anything because you can pretty easily cast a wide net and classify everything as speech.

I can't freely express myself with a firearm and shoot anybody I don't like.

Likewise, governments can regulate commerce. They're generally doing a pretty bad job when it comes to the Internet in many cases, but it's very much not a first amendment issue.
