Once you have that basis, game theory lets you extrapolate. Theft is bad it most cases, for example, because it lowers the overall human good, even if it improves my own particular good.
Governments are useful because they're a way to overcome collective action problems like free riders or tragedies of the commons. Because of this, they can be a force for good.
I have no idea where you got this "turn in police some people, but not your friends and family" from. Please try to limit your commentary to things I have actually said, not things you have imagined.
From your tweet:
@oleganza 1) No, I wouldn't turn them in, but I believe such enforcement is necessary and overall good. 2) No.

So lets say we have different ideas on how to maximize "overall human pleasure" (I also don't see how'd you measure it). Who should give up his idea? Should I force you to follow my recipe? Or should you force me to follow yours? Or could we just agree peacefully on some line in the sand and we try our ideas separately without insulting or threatening each other?
Example: if we develop a software and have different ideas on how to do it, should we fight till one of us gives up, or we can simply walk away to our computers and work with some other people, if we cannot work together?
If you can't hold an honest discussion then why are we here?
You answered: "No, I wouldn't turn them in, but I believe such enforcement is necessary and overall good."
Before, in this thread I asked if you will turn me in, you answered:
"Yes, I would justify someone forcing you to pay taxes to fund the NSA in that case."
So my question was (quoting from above):
"why would you turn in police some people, but not your friends and family? It sounds to me that your morality is not universal at all, but just a whim."
How am I being dishonest here? Please answer what's the moral difference between turning me into police and not your family?
"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?
What would "maximize your pleasure"? Not telling police and they don't extract taxes, or telling police and they do?
Also: why would you turn in police some people, but not your friends and family? It sounds to me that your morality is not universal at all, but just a whim. E.g. "I'm okay to kick people I dislike and not okay kicking people I like".
