It's just that OP's comment makes no sense. Losing a bank link somehow still leaves you about a dozen options that don't involve waiting on coinbase support. If I had half a million in cash stuck on coinbase/unable to ACH home I'd withdraw to ETH/DAI within 10 minutes.

If the goal is to withdraw to fiat, and Coinbase is your only fiat ramp, I don't see how withdrawing to an ETH wallet helps.

And then do what with it? Do you think most people selling land in northern Minnesota accept “dai” as payment?

and then you use a different exchange.

Square’s cash app accepts Bitcoin deposits

Kraken exists

Gemini exists

And if you were moving larger amounts there are dozens of OTC desks, some of which are operated by the above companies including Coinbase.

The point of them mentioning Dai is to have stable value long enough to figure out what the next move is
