Whether it makes individual sense or not, the stadium is still predominantly STH and the current market is driven by that. Without counting them all up (and if someone wants to, feel free to correct me) by eyeball and the reports here right now there are in the ballpark of under 1,000 seats open in the lowers and maybe around 1,500 in the uppers in GA. (Clubs are a different market in NFL economics even as bad as it is.). That's still pretty strong. The secondary market is huge and weak but it is still only a subset of the entire market.
These numbers are interesting because they seem to line up with what the team is doing. If the similarly back-of-the-envelope calculation upthread about how many seats are being removed is right, it's right in the ballpark of the number that's vacant now (and that number seems to be off the now-reduced capacity). Only they know what they can actually fill off the "wait list", but it's a clear effort to get supply closer to demand.
The team will adjust the capacity/prices/etc to keep the market viable, and the future lies in smaller capacity and making the stadium a more exclusive experience - just as it does for the rest of the league as it competes with TV and worsening stadium experiences everywhere. That's also why you now see them making better efforts to improve care and retention of STH. The primary market won't crater because they can't allow it to - that's just basic business.
