If creditors were obligated to accept Bitcoin, does that mean that to be a creditor, you must maintain a Bitcoin address/wallet? Or could you still just say, "Sorry, you still have to pay in USD because we don't have a Bitcoin wallet"?
It's concerning that the government has partnered with one particular startup company with a specific Bitcoin app for this. Depending on how the laws are written, essentially forcing people to use a specific startup's app to transact in the country could be the most egregious example of regulatory capture we've seen in recent history.

If this is actually implemented, there will be a lot of payment gateways which will take the BTC and give you today's USD equivalent immediately (minus processing fees). Pretty much the same situation as paying by foreign card.
If you make it clean beforehand what the repayment terms are you should be fine - at least in a US-style law way (this is why you can say “no $100s” or “you can’t pay in pennies”.
One you’ve a debt and you didn’t specify you may be required to accept payment (though if the debt is denominated in dollars the BTC is perhaps not as clear - does it have to be enough at the time of payment, settlement, etc?).
