Nostr clients without zaps will not stop people from zapping will not stop people from SPEAKING ABOUT zapping.

Imagine using a nice app and hear about people zapping without seeing how you cand do the same.

People will start to use it in browser on pc.. and they will suddenly think twice about buying an iphone again since subconsciously they will realise that instead of "only on apple having a feature" , "only on apple you don't have some features".

It will turn apple advantages in disadvantages at a conscious level.
