It is a bit overkill, but the closest you can get to owning your online identity is to "own" your own domain. sarcastiquotes used because you don't really own a domain you only rent it. I run my own mail server because I am a sys-admin and running a mail-server is something I do for fun. but the amount of agency you gain once you have a domain is staggering. people without a domain are pretty much second class net ci…
but if you stop renting from the registrar then whoever rents the domain next gets access to your email. seems like a horrible solution to this problem. at least i can be reasonably confident that google will never recycle my email address and send all incoming mail to a rando.
What do you base that confidence on? Short, meaningful names are valuable and there is no reason to believe that somewhere down the line they won't be recycling ones that aren't used anyway as premium accounts.
