I started out with 9 relays when I created my profile here. 4 are dead now and Nostr is a lot bigger. I don’t think it’s fair to say that there will be more relays as it grows and not have a clear incentive you can point to for why people will suddenly run more. 

I think all the recent events with Telegram and Samourai should be a clear indicator of where things are going. 

Having many relays doesn’t help if they all have nice URLs and the operators can be easily identified.
