It's still *my* money!
It's "my" money, but in a collective sense.
It's now the government's money, to do with as they see fit.
I voted 3, but it's really sort of a mix between 2 and 3. Once it is collected as taxes, the money belongs to the government. However, since we live in a democracy, we still have some sort of control over what happens to it.
If you build a man a fire, he'll be warm for a day.
If you set a man on fire, he'll be warm for the rest of his life.
