Non-democracy can be considered to be a kind of tax

Despite the fact that anarchists reject the concept of the state there is no reason for them to be indifferent between different kinds of government. Most anarchists would accept that democracy is (objectively) preferable to dictatorship and that direct democracy is preferable to other kinds of democracy. Even anarchists would accept that if the state is accountable to the people then there is less chance of the emergence of tyranny.

If anarchists have a preference for democracy then they will have a preference for proportional representation over first-past-the-post. We (anarchists) would be pleased and grateful to live in a country with at least fptp but would like for the state to give up even more of its powers to the people by accepting pr. With fptp the state has given up some of its power and control to the people and with pr even more is given up. And since when the state gives up power this is liberal and pro-anarchy then anarchists like (direct) democracy. Democracy is not inconsistent with anarchism, although it might be considered inconsistent with absolute anarchy. (Anarchists can argue for full democracy where only partial democracy presently exists, and not be considered inconsistent.)

Since democracy is liberal (the state has given up powers to the people), more democracy is more liberal than less democracy. Liberalism is associated with freedom and a lack of coercion. Taxation is illiberal which means that non-democracy can be considered to be a kind of taxation given that in general the people will vote to be free (from the state). The state has the power to oppress freedom which means that in general democracy acts to enhance freedom.
