I don't see why not though? One of the benefits of a decentralized currency is that it is not subject to censorship by any central authority who disagrees with the content you are purchasing. That is exactly the problem these guys are having. Granted, they'll have to pay a lot of transaction fees/gas, and the volatility still makes it hard to fix prices, but for one-off transactions, you can ignore day-to-day volatility as long as the minute-to-minite volatility is bearable.
