Rightful liberty is unobstructed action according to our will within limits drawn around us by the equal rights of others. ~ Thomas Jefferson
You don't have to be moral or good. There is no requirement there. The only thing people need to do is follow that little pearl of wisdom so nicely stated by TJ there.
Thomas Jefferson had no problem with slavery or taxation. If you are happy to accept his authority, you are happy that taxation is moral as is the violence needed to back up tax demands.
