Can I get into any show I want?
Is there social backlash?
Are there security concerns?
Is the experience the same whether I pay or not? How better or worse?
What's the price of the show, not in dollars, but in work I do for the rest of society?
Do the artists aggregate to my life?
How much does it cost them to be there performing?
If the wouldn't do it, would someone else?
Basically I think your example gets a bit overcomplicated because the current market is heavily distorted by giant recording companies. It is an area that is almost fringe economics because it involves feelings and quasi-irrational judgment of value. Should you ask me if I would steal a computer (not for necessity) or if I would sneak into the bus instead of walking I'd ask mostly the same questions, but the thinking process of the decision maker would be a lot more rational and, therefore, adherent to the models that shape our economy.
Someone who downloads a pirated copy of a work is not similar to someone who mugs someone or lifts a wallet on the street because it requires a lot more to visualize the one's from who you are stealing.
That being said I would like you to retract your statement about me, not because I'm not a pirate or a thief, but because you offended me.
P.S.: This is a place for the discussion of ideas, not for personal attacks. Come up with an argument and I'd be happy to debate the issue with you. Insult me and you will be breaking (again) the two first guidelines for comments on HN
