Part of the attraction of the scheme is not having to queue up to buy
tickets (and also not needing to know the system well enough, including
speaking English, to be able to decide which tickets to buy).

So you'd pay twice as much

Where's this "twice as much" come from?

Capped oyster price for an adult: peak/off peak 8.00/6.60. Cash price for a
child travelcard 4.00/3.00.

So you are assuming a child with a paywave, deciding whether to use the
paywave (assuming there's no child discount version, which may be true)
or get a travelcard? A bit of a corner case, don't you think?

not to queue up, would you?

Have you seen the queues at St Pancras?

It's not always like that

It's often like that or worse. I'd hate to be there just after a
Eurostar has arrived (if I'm on such a train I'll be heading for the
Midland Mainline platforms, not the tube).
