Then maybe is should be forced to say: “Buy revocable license” and require the user to answer randomized multiple choice questions regarding the terms of the license that act in opposition to the purchaser. Collect metrics on wrong answers and if greater than say, 15% of people can’t determine what they are actually handing over money for, fine and require additional clarity.

Or, just flip the tables and say the historical meaning of buy implies transfer of ownership in exchange for some trade. Since the seller no longer owns the items that was sold in the transaction, they have no additional rights that are covered by other areas of the law (such as copyright). First sale applies and if the seller doesn’t provide a mechanism to facilitate that sale, the buyer is free to exercise that right in whatever way they see fit.

Revocable is an obscure word to normal people. It should say temporary.
