What does that mean, then:

"Yes, I would justify someone forcing you to pay taxes to fund the NSA in that case."

I simply don't understand how "justifying forcing me" is not the same as telling the police. If it is not, what's the moral difference for you?

Policing is, in general, justified. That doesn't mean I help them do it.

So you would be satisfied if police finds about unpaid taxes, but would not help them find out? Is that right?

What would "maximize your pleasure"? Not telling police and they don't extract taxes, or telling police and they do?

Yes, that's right.
