Look, I love the bar as much as the next guy, but who has the time, energy, or inclination to put on pants and go outside to get there? Wouldn't life be so much better if the bar was in your home? And you didn't have to pay for your drinks (except earlier, when you bought them from the grocery store)? Possibly. Only one way to find out!
They prop you up while you're propping up the bar. Although I suppose technically your can sit on them when you're not drinking, at like brunch or something. In theory, anyways. I guess as much as I don't see the point of having barstools without drinking, I even less see the point of having brunch and not drinking.
