So let’s go with that analogy shall we? What is the winning move in a restaurant that only serves poop or sand? It’s not to order the sand - it’s to tell them that you won’t eat there at all until they offer good food.
Ah, so youre a "If I don't participate in how the driver drives this bus, I will be safe when it is driven off the cliff" type.
To the metaphor, You must eat at the restaurant. Not eating at the restaurant physically cannot happen. Until enough people consistently vote to eat sand, the 50/50 flip between sand and poop will continue to go on unimpeded. Once sand wins consistently enough, paper will be offered. Once paper wins often enough, salads will be offered.
