Virtual TKTS may seem like a win, but as FishermanBob correctly points out, a discount without a little perception of effort becomes the de facto full price. Producers don't necessarily want to be at TKTS at all, ideally, but that we have them making seats as available as they do at as steep a discount as they do is TKTS' blessing. Yes, ticket prices have gone up, making TKTS's discount prices more expensive accordingly, but that problem is Broadway's, not TKTS's.
But, to address your original post point-by-point.
--Think of the advantages you don't have to rush over to Times Square to get your ticket.
TKTS operates two other locations downtown that are generally far less crowded.
--Than stand in a long queue, which is made worse if it is wet.
This is the effort required for TKTS' discount. Use a discount code if you want to buy at the box office, but it's less of a discount usually.
You can choose the seat you want online.
--The TKTS discount is incumbent on being sold best-available. Use a discount code if you want to choose your seat.
If you are handicapped maybe you cannot queue.
--I don't believe this is a written rule, but I've seen the security guards at TKTS letting handicapped patrons wait at the front outside the line and come right in the front when they open.
You’re never to be harangued by those pushers, trying to offload rubbish shows, whilst you queue.
--Pop-up ads, pop-under ads and banner ads.
If you are a visitor you can do your day trips without worrying whether to get to the booth.
--As stated before, this is the effort required to get the discount.
it's not an idea who's "time will come" - it's an idea that's half-baked and isn't feasible. Come up with a way to make the discount marketable to producers without replacing the full-price as a de facto ticket price and then we can talk.
Words don't deserve that kind of malarkey. They're innocent, neutral, precise, standing for this, describing that, meaning the other, so if you look after them you can build bridges across incomprehension and chaos. But when they get their corners knocked off, they're no good anymore…I don't think writers are sacred, but words are. They deserve respect. If you get the right ones in the right order, you can nudge the world a little.
