"If I offer the dollars, it can't compel me to produce another car or give you a piece of my house instead."

Sure, but if you cannot (or simply do not) pay your creditors with dollars, the courts can give them a (figurative) piece of your house/car/computer/etc.:

Yes, figurative. A lien is an attachment, payable in DOLLARS when the encumbered item is sold.

Siezing property happens as a last resort, but doesn't undermine the fact that a debtor can ALWAYS choose to settle a debt in dollars, and can NEVER compel the lender to accept payback in gold or BTC or potatoes.
