The problem, in the USA for most people, is Comcast. Downspeed hardly matters. It's been plenty for decades. Upload speed has stagnated. I uploaded as fast in 2003 as I do now in 2022. And as others have said, it's not so much about 1 fast provider as many providers and choice. In my comcast monopoly my plan started at $60/mo in 2011 and without any changes on my end and no change in my upload speed that price has in…
This is such an artificial/politically generated problem too. I used to live in Tennessee and there were several cities with gigabit internet that was created by public funding. Chattanooga did this but was blocked from providing access to those that were in unincorporated areas. Even though the city still provided these people other utilities (electricity, water, gas) and mail. Same thing happened in Tullahoma (city next to where Bonnaroo Music Festival is). Then I remember Google Fiber trying to come in but the state had a law where lines needed to be placed in certain areas (which were of course in use) and that one operator could not lay down lines unless there was a representative from those that already had lines in place (supposedly to protect property). But this obviously led to shenanigans. Similarly when I moved into an apartment I chose the faster city internet but the previous tenant had AT&T. When the utilities company came to turn on my fiber (as they had provided for the apt previously) they found that AT&T had slashed their line, which caused me to have to pay an instillation fee. For a state where the people were so proud and supportive of libertarianism and the free market there sure were a lot of laws that supported or enabled monopolies to run a muck.
There are clearly available solutions and there's room for markets to exist and provide competition but it is very clear that we've set up a system that enables the unregulated monopolistic actions of ISPs.
