What about the Nostr scaling issue? Relays are not rewarded (to my knowledge). This is not sustainable. Nothing in life is free. It's fine with 20k WAU, but not at mainstream penetration. 

Also paid relays are not the solution. No one wants to pay to play. That's not "free" speech, literally. 

There needs to be some Tokenization to incentivize relays, and even incorporate clients into the mix. Other proposed solutions? 

 If you are not paying for the product, you are the product. Good question though. 

 La fameuse phrase être un produit nous le sommes plus ... à moins de vivre dans un monastère ..c'est nous qui faisons fonctionner les systèmes soit en travaillant ou autres
