I am struggling a bit to explain this, but I will keep trying until I find the best words:

DHTs needing a bridge to browsers doesn't equate them to Nostr relays, anymore than Bitcoin needing an Electrum server makes it equivalent to a bank.

Anyone can build a bridge, and they still work with each other without knowing (or trusting) each other, that is the definition of social scalability, right?
