Do you agree with just this part?

Not really.

Given a fixed amount of review time per day, the largest deck you can maintain grows asymptotically over time, not exponentially.

Do you agree with the assumptions of the Anki scheduler? That each time you review a card you'll remember it for incrementally longer and longer?

If so then a fixed amount of review time per day will let you remember things for longer & longer.
