Yes. I think so (with admittedly limited knowledge). Though, you mentioning a federation of relays. That could work and make sense. Thousands of smaller relays storing a small part of the data that can then be transmitted on demand. This likely solved for txt. Does it solve for video and photos as well?

Also, Relays can specialized and be connected to as needed. This is looking like less and less of a problem.
What % of the ecosystem needs to be a relay for this to work? 1%? 10%?
How are they compensated?
Also, is there a way to delete but maintain duplicate files? Hummm, I wonder if Facebook, et al do that…. 🤔
X Y Z all upload the same file. The “one” file is stored and just sent to each user on demand.
Next question, how much badwith do relays use per day???!
Good questions lemme think a little bit about them lol but I also like the idea of distributing some of the weight from the client side. For example have priority/non-priority types for notes where the non-priority types can be sent to a different “channel” in the relay kinda like how the lightning network aims to scale bitcoin transactions. Facilitated by the clients
