I don't know how a government would enforce this. Nor if we want them to. Yes, you will and arguably should lose your followers if you move sites, and that's because your followers are passive browsers who don't care about you specifically. None of us are Taylor Swift who will have millions follow wherever she decides to go. That's one offset of anonymity in this case.
Also kind of funny that you mention federation as an implciit solution and then complain about email.

Again, yes that makes sense. you acknoledging that they have better OS's seems to be submitting that there's value in their service. Personally, I can replicate 99% of what I use on Linux and a de-Googled AOSP, but it will vary from user to user (RIP to the artists stuck in the Adobe suite). Having a better service isn't grounds for a monopoly alone, that's just plain ol' competition.
Mandate that services over a certain user threshold expose open interfaces to which competitors can bind. That has worked reasonably well in banking and telecommunication.

Unlike Mastodon federation or SEPA bank accounts, there is no legal requirement for the old service provider to assist in moving accounts, and I was talking about Googlemail which ties an entire person's identity across a multitude of services to one account. The person in my scenario lost everything from their mail account to the apps bought on their smartphone.

Agreed but there have been many cases where the "better service" just bought up the competition. Adobe is the best example, and up next I'd classify Atlassian. Both of their respective stacks still show the signs of integration after decades.
Were capitalism regulated, I'd agree with you - however the reality is that capitalism these days has devolved into monopoly and rent seeking:
Unhappy with your phone and especially internet provider? Good luck finding a new one, in most cases there is no competition at all or it's just as bad. Unhappy with your social network, say because there are too many Nazis and conspiracy theorists running rampant? Bad luck, no federation requirement means you'll lose all your followers and they'll lose you. Unhappy with your bank? Competition is just as fucked up. Unhappy with your railroad transport provider? Tough luck, they own the rails so you can't get another company to ship your stuff. Unhappy with your phone or PC operating system? Good luck, in the best case you just have to buy all your applications again (if they are even available at the competitor), in the worst you'll have to live with frankly sub-par open source alternatives. Your email provider banned you because you sent a photo of your naked child to the pediatrician? Even an international media outrage won't help you get your account, your digital life back.
The list goes on and on and on, and the common point is that anti-trust enforcement has gone completely down the drain.
