As one of the "overseas mitherers", I happen to agree with you.
But unfortunately, there are too many in the ST database who see having a ST as some sort of (o(k-extension with which to win piissing contests about Ueber-Fandom with.
Let's face it, the way things are with attendance, you stand a superb chance of getting your seat or the one next to it even if you pay on the door, so that's all having an ST is.
A chance to wear a badge that says "I'm a better fan than you"
