I disagree on the decentralisation topic.
If you're intending to be in control of your data, you have to live as isolated and independent as possible - no verbal or written exchange to other people, no shopping (whatever goods you need), grow all you need by yourself.
Are you in control of your life then? I don't think so.
And I don't think you should start making videos about that decentralisation stuff when your objective should be to sort that tax issue out.
