I've been contemplating that recently. You're of course correct that subsidized tokens won't be forever, but that might only be half the story, since there's two opposing forces in action:

1. Phasing out of subsidized tokens.

2. Token prices being brought down through scaling, better hardware, etc.

It's possible that these might balance each other out sufficiently that token customers won't notice any substantial increase in price.
