This license assumes that the code is valuable like before. Once you have the behavior known, independantly writing code that does it is now trivial. Hence there's no real need for this in the market.

Tokens ain’t free so even under that logic it’s still at least that valuable. But also, “Once you have the behavior known” is discarding a lot of value. Much of the value in software is not someone’s ability to program but what they have decided to build.
