You could interpret tradition as a consensus vote of the democracy of our ancestors.
How much of that tradition was really created by a vote? If it wasn’t, why should I treat it like one?
Just because people did something in the past, it does not mean they all thought it was a good idea. (It could actually be one of the reasons why they later stopped doing it.) Also, people in the past didn’t have some of the information we do—why should I expect that given that information, their votes would remain the same?

See Nick Szabo about intersubjective truth, and Chesterton’s fence.
On the other hand, just because something was a good idea in the past doesn’t mean it’s still a good idea now if things have changed.
