Certain journalists and / or whistle blowers could be tracked simply by watching accounts.

That sounds ominousAF, what would that look like, on a hypothetical?

Some people would like to keep income private to avoid taxes from their governments. I think there is nothing wrong with that. I would like to see platforms like this dissolve governments and I'm pretty confident they will.

That's called Tax Evasion. If you want to challenge taxes the last thing you want to do is evade taxes, if you don't want to pay taxes there's exemptions and exceptions and procedure to Revoke your Benefits as citizen(a term of servitude) and therefore the burden of Taxes won't apply to your income.
