It's illegal to buy dollars but not assets that track the USD dollar. Buying DAI is legal for the same reason buying USD denominated bonds is legal, they are not dollars and you are not taking them from the central bank.

And either way I don't think grouping "criminal transactions" with "stuff that's illegal in X country" is fair. At many points in history governments outlawed things that are very wrong (e.g. nazi germany) Just because someone doesn't want to succumb to corrupt institutions doesn't mean he/she is a bad guy.
