What do you mean by no longer decentralized if it has 4 gigabyte blocks? Storage capacity should be no problem for decentralization if the capacity of SSD grows like in the past

It's not about the storage it's about the bandwidth and infrastructures. If you have 4 gigabytes blocks only few percentage of individuals would be able to run a node. Look at ethereum network. Today you can run a bitcoin node on your phone because we have small capped blocks.
Never heard of a full node on a phone. Can you name one?
Monero is far away from 4 GB Blocks. Let's see what solution will come up, if monero hits 4 GB blocksize.
What a great problem to have. Monero is used so much that it is hitting 4 GB blocks 😂
Don't think we'll see that anytime soon if ever...
