Those casual users that vote fewer times create less value. Limiting the ability to create value to the lowest common denominator kills the ability to create value.

Why limit votes at all? If I spend the time to make 100 votes, didn't I create value with those votes?

I don't see value in funneling wealth to the already wealthy and skipping the content creators. I see value in creating a platform that increases in value, this adding wealth to the wealthy who have invested in the platform.
