Why are exchanges/onoff-ramps needed??

Mining, swaping, burning, spending is enough. And where it's not, the use-case is not decentralized (has centralized governance or has known membership) & can be achieved more efficiently via fiat.

How can I buy bitcoin, to pay the ransomware if there's no on-ramp?

Nice tongue-in-cheek joke. Don't. At a given time, you are to be crypto savvy & be protected in the first place or don't be crypto savvy & use the legal system with fiat for better efficiency & solution

By accepting bitcoins on your onlyfans page.

Tell me with a straight face that you'd voluntarily buy something from China and send them crypto for payment.
