It's not. Basically it doesn't have a high accuracy. We don't need the fastest blockchain or something like that. If waves can still be considered as security and what's the differences?
You should put the main concern on the utility rather than scalability.
It's no good having 'utility' as you say, when the network is slow and congested.
Fast transfers, payments and airdrops etc are a big factor in selecting which platform to use for a utility token.
