They can make a big one if there are too, too many of those small votes. Otherwise, it's not money (meaning money to be used to purchase our goods). In any way, I only tried to explain the possible reason why it exists so small votes.

Yes, we can imagine thousands of small votes (even if it could be rare to happen).

But it is how Steemit should function.
