People's lives are still highly centralized and many are becoming more so, even with Bitcoin, with Nostr and even trying to escape forms of control... Especially if someone is poor and from a highly repressive country.
After all, in general, it is always much easier to destroy than to build. All it takes is for some crazy person to decide to take everything that is yours.
Therefore, even if people come to Nostr and use it, they will always establish some point of stability and will make fewer and fewer changes, because every change always requires more time and dedication.
Another point is that because it is an anti-crisis network, its main use ends up being to provide more repressed information, that is, Nostr ends up being driven by news of risks and disasters.
And even with this use, it is not always worth posting, because if the person posting is poor, without Bitcoin, without prominence and from a destroyed country, no one cares and 'freedom of expression' will be of no use. It will be like talking to yourself.
