Your online identity is owned by your email provider (2019)
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 citizens.I wish municipality offered domains, for example: you move to St Louis you would get name.stlouis.mo.us this would give you the same agency online that a mail address gets you offline.
