There isn't much that is subjective about paying the appropriate amount for the services and programs you benefit from. If you disagree that you should pay $5 for a cup of coffee that costs $5, then we have some very fundamental differences and can't come to any agreements in this debate.
>>We don't legislate morality.
On the contrary. Murder is illegal because we have decided as a society that killing people without just cause is immoral.
>>I didn't ask for these services.
But you still benefit from them, either directly or indirectly. A homeless shelter benefits you even if you aren't homeless, because it takes care of the homeless and makes it a lot less likely for them to commit crimes for survival. A fire department benefits you even if your house isn't on fire, because they put out fires in neighboring buildings and prevent them from spreading to and burning down yours. You are part of a society, and taxes are required to maintain the proper operation of that society, whether you have asked for it or not.
