This isn't a uniform truth about taxes, even aggressive ones: the evidence so far around marijuana legalization has been than consumers have been more than happy to pay high taxes, because the net cost of marijuana is still similar to or lower than the pre-legal cost.

We might eventually see a variant of tax stamp fraud for marijuana, the way some states do for cigarettes. But that's just the nature of these things, like you said, and I think the general trend is a "win," in terms of eliminating WoD policies.
