The analogy to voting to flawed in that actual voting is much too powerful, because it involves politics and the use of force. When you "vote" with your dollars your choices are to either support something or ignore it and spend your money somewhere else. The amount of support you can provide is limited by the economic surplus you've created, and no matter how much money you amass you can't just shut down something you dislike as long as other people continue to support it. Voting in the political sense lacks these safeguards: a majority (or vocal minority) can subsidize their pet projects with the opposition's resources, or prohibit harmless activities merely because they find them distasteful.
