I would urge you to think of the idea of intentionally living with a rigid or punitively expensive cap of daily transactions.
Why should I if I don't have to?
Crypto-units are not intrinsically rare (competition abounds even amongst Cryptonote coins), although what appears at the moment to be rare are designers who can solve all the fundamental issues.
Anybody can create a shitcoin, but
useful cryptounits may or may not be intrinsically rare. It depends whether what rpietila is saying has merit. Perhaps it is not possible to fully solve issues of "bloat" with any coin and also provide other attributes that people want in these crypto-units (privacy and liquidity for a start).
If that is true, then the units might not be rare but blockchain space might indeed be very scarce (and then must be somewhat expensive). It is a useful perspective.
