I think that strip clubs are definitely under pressure zoning-wise. I doubt that you'll see land zoned in city cores for new clubs; and as land becomes more valuable for development, you'll see downtown clubs shut down.
Strip clubs are also facing market-share pressure as new "entertainment" options, especially those online become available. The question is will they be able to survive with their new, decreased market-share in the long-term?
Personally, even with other options available, I still like strip clubs. For one, they're one of the few places where one can feel comfortable going out in 'public' all by oneself. Second, it's a huge ego boost to have beautiful young woman approaching you and asking if they can join you. And I actually like the fact that contact is limited. There's no rush to a "main event", rather you can experience all sorts of wonderful and creative stimulations. Finally, with one night out, you can have all sorts of wonderful variety... or find a favourite and spend lots of quality time with her.
