Imo Nostr needs to be 'pay to post' like Stacker News to be a quality, sustainable social network or network in general.

Are there tradeoffs to being 'pay to post'? Hell ya.

But the long-term benefits are tremendous and the 'costs' can be minimal relative to the long-term value provided to everyone on the network. Bitcoin is a great example of this (the 'fee' market) and so is Stacker News (at least outside of Cowboy Credits).
