Company scrip is a problem because the tokens are usually artificially priced by the issuer above their market value. If Walmart tokens in Mexico were traded freely, they would have had non-zero value (the ability to buy something at Walmart is better than nothing), but less than their face value. The same thing happened with government money many times, so there's nothing new here. Having a law to always accept some currency in some jurisdiction is convenient, but non-essential (given the availability of exchanges and overall liquidity).
