Curious, why do they take helping poor oliver as example, and not say, paying for the military?
Do you think its okay for george to refuse paying for roads, for the police or the defense of his country, or even speeding tickets if he doesnt want to?
If george doesnt like paying for military, or speeding tickets, or helping people in need, in a democracy he has the ability to vote.
If he doesnt like the outcome of the vote, he can move elsewhere. You dont get to cherry pick laws to obey or things to pay for.
So I think there is a pretty good real life analogy.
Oliver bought a projector, the bulb burned out. A new bulb is about $300, which is a rather large purchase. His roomate, George, used the projector all the time, and was responsible for a significant portion of the wear and tear, but claimed to not care if it got fixed or not. Oliver personally wants a functioning projector, and knows that george will be able use it if oliver pays to get it fixed. Should Oliver:
1) Try to peacefully convince him to pitch in
2) Just go ahead and buy the new bulb himself (knowing George will get a free ride)
3) Not purchase the bulb and just go without a projector, even though he could afford it and it is something he wants.
4) Violently force George to contribute to the fund since Oliver "knows" he will use the projector once it is fixed.
5) Strike some deal in which George agrees he no longer has use of the projector (and trust him not to cheat).
6) Lock up the projector when he is not around so that george cannot have any use of it.
7) Anything else?
