I’m sure it’s all of those things. But imo the biggest culprit is traditional social media that has trained our lizard brains to be addicted to what it has to offer. It’s hard to make a commitment to Nostr while you have your old twitter account waiting to go back to. I became Nostr only right after I burned the bridges behind me. I simply had nothing to go back to: no twitter, no FB, no insta. Felt uncomfortable at first but I wouldn’t be want to go back any of them now.
