I would probably be willing to pay for a better connection that what the government would provide as standard if offered because I spend my entire life online, I'm sure there will still be private ISP options with USPs to suit how I use the internet.
In the end that could easily give consumers more choice than they get now in areas that have poor coverage (where they usually get the option of a <4mb ADSL connection or 3/4G Celluar). Instead of areas where they can get Virgin Media, FTTP, FTTC, or 5G coverage.
We still have insurance companies and private healthcare here, it's just most people don't use it because what we pay for any way is good enough. So then the private ISPs just have to offer something better.
Hard to argue with that conclusion when there's only one option.
I.e. it would be the only option only if other companies bring nothing better to the table.
