Attacking Nostr "because you can" is like pouring red wine on a wedding dress simply because you’re able to do so. Technically, you might have the ability to take such an action, but that doesn't justify it. In both cases, the act causes harm to something others care about, with no constructive outcome.
The wedding dress is a symbol of an important event, just as Nostr is a platform that a community has built up and invested in. Ruining the dress—or in Nostr’s case, disrupting the user base and causing people to leave—serves no purpose other than to destroy the hard work and joy of others.
The argument "because I can" overlooks responsibility. Just because one has the ability doesn’t mean it’s right to use it in destructive ways.
