Is it legitimate for people who are being taxed without direct representation to start a revolution?

Yes

Explanation:

I mean, The United States did it, and I’m assuming that is what the question is referring too.

America was thousands of miles from Britain, and had no power over what happened to them. They held no representatives in parliament, so they had no control over what happened to them. I think it is completely sensible for the colonies to be upset over that, enough so to throw a revolution.

it took two men to wrestle rome back from chaos and turn a republic into an empire. in the first century bc, rome was a republic. power lay in the hands of the senate, elected by roman citizens. but the senators were fighting for power between themselves.

im the bozz no matter what
