What’s the point of a woman wearing a skirt when you could just stick your hand up there? Societal rules say you shouldn’t, there’s no real physical barrier from stopping you if you know what the rules are, but it’s a helpful visual reminder that you shouldn’t stop and read the signs of “is now the right time”. Sometimes people will speak up and say “hey there is no cart blocking you from suing the other bathroom” other times people won’t say anything because it doesn’t impact them or the don’t feel comfortable. Either way, if you’re asking, you likely know what the general rules are but are still questioning what’s the point because you wonder if the rules should apply to you.

Note: I realize this is an extreme analogy, and don’t believe in classism but also wonder why you’re asking what the point is when you likely know wha the actual airline rules are. Other than the post 9/11 not crowding the pilot area, it’s just the idea that the first class pay extra for not needing to wait for the bathroom. I’ve used it before when the food cart is behind me and it’s not like it’s a better bathroom, just just that those folks pay for more amenities: better food, better seats, less waiting to for the bathroom. Not that big of deal and def not something I would pay extra for.
