Due to a well known law of headlines I'd reply No, but if you copy Europe the answer will be Yes. In this case Europe has the advantage of a fragmented market. Different countries, different languages, different operators and different regulations led to competition. No pan-European monopolist.
I don't know if this is widespread (I think it is) but where I live (Italy) unbundling is mandatory and we have new operators using the cables of the former monopolist. In some areas the former monopolist is using the cables of newer companies. There are at least three different fiber networks, unfortunately not particularly fast. 100 Mb/s download and 10 Mb/s upload is the norm for fiber (ADSL goes up to 20 or 30 Mbps with the usual caveats of that technology). I got the feeling that the operators agreed to settle on that and save some money. Fiber was at 10/10 Mb/s 14 years ago. Competiion is never enough.
So, I don't recommend breaking up the US and switching to lots of different languages
