The real problem with the striking down of net neutrality is not what is provided, but what is moved to the slow lane, in my opinion.
The reason the telecomm carriers, and Verizon, Comcast, ABC/Disney etc. want it stricken, is they want something for nothing, and the chicks for free.
Most fiber in the US is run along government-owned right-of-ways. That means the carriers don't need to pay rent on the land. You the taxpayer give that away. Thank you for your generosity.
The bandwidth of the fiber is limited by several factors; Condition of the cable, number of strands originally laid down, the capacity of the nodes attached to it, and etc.
Rather than paying to lay down new cable, the carriers and major providers want to usurp available bandwidth to their highest-paying customers.
While you might like to play an online game, or make a video call to an ailing relative, that doesn't earn a lot of money for the carrier, or the ISP.
It needs to be downgraded, to allow PPV movies, and sports events, etc. to be broadcast to those willing to pay premium rates, for the cable that is lying on taxpayer land.
With the loss of "net neutrality", access to the fastest cable speeds can be shuffled by the carriers and sold off.
While that's bad news for hospitals and fire departments, individual users, libraries, and conceivably people in smaller population centers, it's great news to a porn provider, in a major city, who wishes to stream porn, and has the ability to pay. (Let's not forget there's a LOT of money in porn!)
It means that gamers and general users who have time-sensitive material, will now have to pay higher rates to their ISP's to not experience lags, created by insufficient bandwidth. Wall Street brokerages, Gaming servers, and the like will be forced to pay for higher speeds. (Sold separately by the carriers.) in order to not lose customers. They will, in turn, need to charge more on a monthly basis, to cover those costs.
Anything you want to access, should (barring censorship) still be available somewhere on the net.
It will be slower, and subject to dropouts, but it should still be there.
Good luck to us all.
