No, if I borrow your car (as a loan, with 100% interest) and refuse to pay it back, the court can seize the one car car, or order me to pay restitution in dollars. If I offer the dollars, it can't compel me to produce another car or give you a piece of my house instead.
"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.
