I use a similar trick to the scheduling - if I'm undecided, I just start and do all the weighing up while I'm getting on with it. Once you've started, chances are you'll continue as you've already done the hard bit. If not, you don't feel like you've cheated, which, for me at least, is for too easy a habit to fall into.
1) I am boycotting first and foremost. If I were unable to listen without paying (as indeed I am for a significant portion of my obscure tastes) I still would not pay. The fact that I still listen to music I like through piracy is a separate issue, IMHO, because of this. Like I say, whenever I find music I like with no industry involvement, I pay for it without giving piracy a second thought.
2) No, I'm OK with you taking the car, as long as the original is left where it is. If you can't think of a way to do that with a physical object such as a car, then your original analogy was flawed.
Again: If my employer didn't pay me, the time that I had worked for that pay would not be left untouched and marketable - it would be gone, ie, stolen rather than illegally copied.
The lack of loss of the original is key in the piracy debate, these analogies are flawed because they don't analogise that key point.
Piracy is a loss of potential market share, not a loss of something tangible like a car, or my time. In my case that market share simply does not exist - I have deprived the labels of nothing that I haven't already deprived them of through my boycotting.
Expense is not necessarily in absolute terms, it's relative in my case. I outright refuse to buy label albums because I won't support the music industry as-is, I'll only buy music if the people who made it get the vast majority of the money. Have you read Steve Albini's take on the music industry? It is entirely accurate, and I will never put my money into keeping that system alive just on principle. Anyone who has ethical problems with piracy but not the music industry either doesn't know the music industry, or doesn't know anything much about anything, IMHO.
PS: Last I heard, when you take a Gallardo that you're not entitled to take, the original one disappears. Piracy is not the same as theft.
PPS: I say all this as a semi-pro musician trying to make it myself, and not quite managing it yet. I don't begrudge people who've downloaded my music without paying for a second.
