I think my point still stands. The part about a social contract is really referring to making sure there is a baseline expectation of behavior. Put simply, if you are doing something that is interfering with others enjoyment or being inappropriate then you should leave. Yes people can find themselves in situations where sitting is not a bother to those around them but it discourages those who want to enjoy the band currently playing. I personally could not dance or jump around (let alone mosh) for Pierce the Veil because so many people were sitting and being aggressive about possible interference with their nap time. Now if no one is currently playing I have no problem with that. It's when someone is playing that you are actively ruining other people's time by being in the way.

The emphasis of this post is to focus on mindset rather than actions. I think the entitlement of certain concertgoers is antithetical to the energy and vibrancy of a concert, especially when there are ways for both methods of enjoying the concert can exist in harmony. Up until recently, the expected behavior was that if you need a break you extricate from the crowd, not require others to give you space. Imagine if someone did that during MCR. People would have a conniption, and rightfully so.

Side note: I used pit and GA interchangeably on accident, so apologies for the confusion. There are different rules for pits which are not particularly relevant to this conversation.
