Not really. You can abstain from voting but not from paying taxes. And if you abstain from voting you will still will be subject to the authority of whoever get's elected and it will probably not be in favor.

> In the market for food, shelter and clothing it's not possible without serious harm to your health.

You can grown, build and craft your own. It's not always practical but you have those options. e.g. I cook my own food and grow produce in the backyard. And we all have way more and better options for food, shelter or clothing than we have for president, governor or mayor.

> Also vote costs you nothing and oa the same for all people and your voting power in the market is directly proportional to how much money you can spend.

I don't know in which world do you live but that just ain't true. Elections are super expensive. In Brazil public funding for political parties is a 10-digits figure. Money win elections. Rich rent-seekers "donate" massive amounts to candidates legally and illegally to later receive favors.

> It's not similar. At all.

Free market is the purest form of democracy. Representative democracy is garbage.
