It's been already explained to you how it is possible to have instantaneous transactions for a cup of coffee. You don't need confirmations for micro transactions as long as you know what you're doing.

That's not to say that faster transactions are not useful (thus Lightning, Casper, etc) but you two whales are completely missing the point with this one. ION doesn't offer any use case for its "fast" transactions, and all known future plans evolve around off-chain features anyway (electrons and stuff).

Let's revisit this when you can actually buy a cup of coffee with ION and let's see then what affects adoption.
