Note I never said porn was better than stripping. I am merely pointing out how much more expensive stripping/ Istripper is than porn...so it NEEDS to be MUCH better
I get your argument, but iStripper has an incremental charging model. Subscription sites will be better value, if you really want to store 40,000 minutes of entertainment, but the math doesn't work if you only need, say, 6,000 minutes or 100 hours. You can't evaluate entertainment products based on cost-per-minute.
Also, the OP's point didn't relate to cost, but content. Girls dancing can be regarded as entertainment, but watching a pair of hairy balls pounding away is a profoundly different experience. The XXX part of iStripper is porn, but it's just a small part of the overall offering. it would certainly be expensive, if you purchased for those 6min SE clips at the end and ignored the rest, but I doubt many people do that.
So I don't agree that striptease needs to be better than porn, or that iStripper is more expensive. It's just a different product.
