Strictly speaking, you are correct. If we engage in cat barter, i fail to render the cat due you, and you petition the Court to be made whole, the Court will award you the dollar value of the cat.
You may safeguard against such trickery by further narrowing the terms of the contract by specifying the accepted payment method to be *exclusively cats,* thus making article 2 of the UCC inapplicable due to exception clause § 2-102.
If the person selling the cat fails to deliver, the court will order them to supply the cat if at all possible, and the dollar value of the cat only if the cat itself cannot be supplied. But that is backwards, because we aren't talking about cats becoming money, we are talking about BTC. Since BTC is being used as money in this transaction, the court will not insist that BTC actually be delivered.
You've chosen to introduce a new term, "money," without defining it. You obviously do not mean "legal tender," as you clearly state below. This breaks the conventional understanding of the term, so what, may i ask, do you mean?
Will this money be one of the many moneys?
Will this money be fungible?
With other monies, e.g. dollar?
Could it extinguish all debts, public & private?
Will a calico tabby be an instance of this money?
Will my IOU?
Legal tender is, by definition, fungible, thus the counterparty *always keeps the option to compensate you in dollars, rather than bitcoins.* As we all know, the FED prints as many dollars as it darn pleases. You propose to devalue bitcoin by putting it on par with that paper trash. Are you a FED infiltrator?
Where on earth did you get the notion of granting legal tender status to bitcoin? And why would it be at par value? I talk about removing legal tender status from federal reserve notes, so that people can insist on getting paid in bitcoins, or whatever else they want.
