Democracy is NOT about people getting government to do stuff, regardless of what. It is about using the people's collective diversity and stability as one of the CHECKS on the government over-extending its power in any direction, i.e. throwing the bastards out.
It ought not therefore to matter if people in general were 100% wrong or 100% right on anything besides their judgement of the over-all state of affairs as affects they themselves (which is the only thing most of us can be trusted to grasp accurately at all).
Leave arguments about harm to lawsuits for damages. Let those who think they can mobilize capital, workers, ideas, and organization to produce goods and services that will provide an attractive investment attempt to do so, whether they frack, nuke, gene splice, rocket, Uber, burn coal, or whatever. Those opposed need not buy. Those damaged can sue. Those providing allegedly more attractive alternatives can try their luck too.
