It doesn't sound like he dislikes it, he's just pointing out that if you get hacked (someone gets a hold of your private key) you now permanently share your account with the hacker and there's no mommy and daddy to call up to kick the hacker out and "change your password" (private key) And it's true. But also: the hacker can't lock you out of your account either unless you also lose your private key. So you can always tell your followers where to find you if you change accounts. Of course, you have to prove that it's you posting because a hacker can also post accusing you of being a hacker and re-directing your followers to a different account...
With more sovereignty comes more responsibility and less help. But I think it's worth it. We just need to NORMALIZE NOSTR CLIENTS NOT REQUIRING YOUR PRIVATE KEYS!!!! Because every client is a new way to get hacked and if your private key ain't in there, the damage a hacker can do is limited.
