No, just the opposite, you are arguing that the majority can tyrannize a minority. A minority voluntarily and peacefully withdrawing themselves from the union doesn’t force the majority to do anything against their will or abrograte any of their rights. On the other hand, a majority forcibly keeping a minority in the union against their will does both of those things. So “tyranny” only really applies in the latter situation.
This is one iteration of the democratic tyranny that our founders wanted to avoid by forming a republican government.
Again, you can withdraw all you want. You just can’t force the sovereign body of the people of the United States to give up their national territory when you do it.
This quandary is of course exactly what Lincoln talked about at Gettysburg.
Any government from which a minority can withdraw at will cannot “long endure.”
That may be fine with you, but it is an issue.
