Google doesn't let you Takeout when you don't allow Google to track your browser. It will give an error to "please use a device you regularly use" even if you can see in your account that there are no other active sessions that you could possibly make use of. I tried a few hours later with the session still open but no dice. Guess I'll have to find a human to talk to at Google in order to get my data pursuant article 15, GDPR.
I have very little hope indeed that they will let you do a takeout without finding a human to talk to when your account is locked.
For what it's worth, Facebook does let you do this. You login, get a message your account was banned for no apparent reason, and that you can download a copy of your data. Unfortunately it's broken (screenshot: https://dro.pm/a.png) but hey, there was an attempt.
