> Why assume that? Could you not imagine that legislation is often meant to signal values to voters as much or more than it is intended to solve real problems.

You mean something like, to signal to voters they're trying to solve a problem voters want changed? Or a problem voters say they have?

I didn't mean to imply it would fix the problem, or that the problem would be fixed. Just that there's desire for [thing targeted], is something enough people would want to change.

I also said "assume that" for the sake of the argument/discussion given you started by saying you didn't understand. I say it's trivial to understand if assume there are other incentives where destroying the product is desirable. Thus making the incentive you mentioned, not very strong, (in context).
