A low cost interaction can have incredible value, that is correct.

Most notes are not zap worthy, that is also correct.

But it is also true that an interaction can have different weights in different conditions (or different markets). A word by Trump has bigger value then a mine, a note its the same. He can reach more eyeballs than me thanks to reputation and/or following. Are his words more useful than mine? Maybe, but what if they are not? He still have the power to continue to say unuseful things, I have not.

So how can I get more power? I change method or technology, I find another way to increase the reach of my words by channeling energy in a different way. That's way a premium in the costs of the interactions is a way to change the market where I'm playing at.

With a premium, I would be able to speak in the table of the "adults" even If I have no reputation or friends in that table. That is a very powerful thing.

Advertisers are "wasting" money every day to try to get my attention, the more they spend, the more probable is they get it. If they spend it wisely, and I buy their product, that's a win/win. It is the same concept.

I would like to have someone spend sats in order to comment my notes, in this way, they have something to lose, and if they do it, it means they really think their comment is worth the sats.
