It's not that "money can buy votes," but for a given party money can buy facilities (offices, transportation, food, etc.) and people (activists, coordinators, etc.) and that can bring (not buy) votes. Printing one "Rodriguez 2027" sign and putting that on your front lawn can be done for free at someone's office; printing ten million of them is a major financial, logistical and organisational undertaking, all of which costs money. Printers, truckers, warehouses, coordinators don't care how many "fucks" you're giving; they just prefer being given dollars to being given "fucks."
Maybe you have more ... workable (?) solutions than "let's get everybody to give a fuck and vote in a different way"?
That's why political parties were invented, so you don't need to create name recognition for every candidate.
Those signs aren't changing anyone's mind. But a party is something people can talk about and understand. It's unifying.
Giving a fuck means engaging with party politics and making it part of your day to day life (at least during election season).
Signs are the laziest and most inconsequential way of supporting a candidate. By far the best way is to convince everyone that you know in person to vote for a particular candidate.
