It means you only need to work with economic disincentives for those who are serious in transacting versus script kiddies.

One man making one-five-ten transactions with, say, a 0.08$ fee won't go "bust" by paying these low fees.

One man that doesn't really want to transact, but has the intention to spam the system with, say, 1 million transactions => that would be another issue altogether because he'd be required to pay a minimum of 80.000$. It would harm his wallet so to speak.

Still, you have large actors that could pay the 80.000$, or 8mn$, or 80mn$, but at least you got rid of the script kiddies.
