The marginal cost of distributing an additional copy of his work is minimal, and his pricing reflects that, and makes people more likely to pay for it rather than steal it.
Can you elaborate on why you don't think this is a general solution?
Louie's just doing for comedy what have been doing for years, recording the concert and selling it at the end of the night or online for more than they'd have made otherwise through traditional distribution deals.
This works for him because you, and i, know and (probably) appreciate his humor, and he's going to make some money from it.
It's not going to work for someone who's not quite as good, and rely more on having that product actively sold to you ...
For a lesser known artist or comedian, you lose the power of the distribution channel, but you gain in margins. The opportunity for cross-promotion in the form of an opening act is still alive and well, and I don't see why it can't continue in a digital form.
Someone (you or another user) is down-modding my comments, and i can't really understand why. I feel they contribute to the discussion (a feeling confirmed by the simple fact that you've engaged with and responded to them). Judging by your profile, it seems like you too are against the idea of down-modding simply because you disagree with an opinion. If you are the one down-modding me, I'd consider that both hypocritical and shameful, but I'm not one to jump to conclusions, and will happily give you the benefit of the doubt.
On the downmodding thing, the only thing to do is thicken your skin. The moderation system here is bloody stupid, inferior to moderation systems from 10 years ago. I'll not rehash my further arguments against it, you've already found them :)
