I understand the argument and you certainly will keep anti-capitalists away with #onlyZaps.
In nostr, likes and zaps are gigantic +500B messages to add 4B of data (utf8 or amount) to a message. That's why many were against likes even before zaps were a thing. And then there is those who find a like too cheap to even show. Vanity stinks.
Zaps at least carry value, so it's less cheap to zap than to like but if you have no money to spare, zap one sat. It's as good as free. But anti-caps won't do that ever.
