A person can work pay taxes and drive at 16 but not vote. Taxation without representation! Wait what?

As i recall this exact situation resulted in the American revolution. Now its age based discrimination and youth being exploited. Workers\citizens should be able to vote. If i can work pay taxes and drive at 16 why cant i vote?
I can consent and be enlisted but i have no say in my own governance.
I can die for my country and have a child but i cant smoke a cigar? Wtf. Get it together America.
No taxation without representation!
These are real issue here at home. Why are we spending trillions of dollars on military operations in other continents?
