You're kicked back, but it still creates artificial urgency in the sense that it's applied to shows that will take weeks to sell out any given section.

That wouldn't be so bad (airline tickets are similar) except that the "best available seats" function is very unreliable, and sometimes the only choice for picking seats. With no 'new seats if available' option, you're forced to pick blind and under time pressure whether to give up what you have for the possibility of better seats.
