Voting for politicians (if you even bother) who might someday vote for or against something like this is a far, far weaker signal, if any at all. Politicians can easily do things that are vastly unpopular - e.g. in the UK the mass immigration that is clearly deeply unpopular but politicians refuse to change it.

Funnily enough, these regulations were made by policy makers who were voted in with votes, and put such a regulation to its own vote. It's the most democratic way to approach this.
