I answered no to the first question.
Everything that is beneficial to me is morally okay. including stealing, raping, and unprovoked murder.
In most cases its just not beneficial to me as for some odd reason gets pissed at people doing stuff they consider immoral, and thereby forcing their moral views upon others.
How are you still not in jail?

is it good for me doing stuff that could get me in jail?
It's not good for you to be doing stuff that will get you harassed, beat up, and shot, either, so it won't really matter what form of government, or lack thereof, you live under. With you specifically, other people will keep you in line, regardless of whether they are police, or just pissed off strangers.
i think you got the point.
just because i think that murder is morally acceptable, does not mean that i have to go around and kill people. because its not the optimal strategy, but why disallow it, and artificially limit ones ability to act?
