I don’t see how the network can ever become self-sustaining if attackers only need to create more transactions than everyone else combined. Sure, as usage increases, the number of transactions an attacker would need to produce increases as well, but so does the attacker’s potential reward — since there will be more IOTA users against which he can double spend.
It introduces a high degree of centralisation - and we don't know the how network shapes up as a consequence.
And the second problem is obviously the unaudited,"quantum resistant" function.
