1. You can name addresses yourself (just like you can name wallets) that is up to the user

Users could index the websites (vote thumbs up or thumbs down) so they can find the better youtube.com/whatever (like a darknet directory with levels of trust)
1. If you meant vanity address, then overall domain is still long
Your idea is feasible if we compare it with darknet (such as Tor and I2P) which also don't have user-friendly domain.
But not when when we compare it with clear net which could have short, attractive and rememberable domain name.
"There are 2^160 possible address combination (excluding P2SH and Bech32 address format) and chances for address collusion is near zero."
It needs to be 0. I can make around 100,000 accounts a day or maybe in a hour or less actually on my household computer just running 1 bitcoin wallet and 1 auto clicker, Imagine a super computer multi boxing the same wallet 500x-500,000x or more.
0 (Zero) probability? It's impossible unless we switched to cryptography where collusion is impossible (
if it's exist)
Why not have a "if address already belongs to a user, double the AES or P2SH and Bech32 format" (sure address would be long in future but at least we won`t get duplicates)
"if address already belongs to user at double, triple the format" and so on.
or "if address is already in use, reroll address" - "if all addresses are in use double amount of characters allowed" - "if all addresses are in use triple amount of characters allowed"
Does this make sense to you?
Yes. Read my reply above.
Also, what stops user to modify wallet source-code to prevent "reformat address" when collusion if found?
