Wouldn't this just be the particular exchange making the decision though? Just, the exchange voluntarily deciding whether or not to accept the trade? Or did they mean that if the coins were tracked regardless of who they were passed to or through how many people? I don't see how a person deciding not to trade with a given address(govt), or any address that traded directly with that address(person who bought from govt), is creating any sort of infrastructure. It could be worked around with by additional transfers of course, or just used directly to purchase things, But in at least one similar type of thing I don't think it would inherently cause or require any harmful infrastructure/modification to infrastructure, even if it would be pointless.
