From what I can see, none of the people talking about this understand the decentralization of bitcoin either.

Bitcoin decentralization is directly proportional to the cost of running a node. Cheaper node = more decentralization

Has no one noticed how much more computationally expensive it is to run a node since the spam started?

How many Raspberry nodes have left?

Now imagine if the restriction is removed and we allow spam.

There are people who run a node because we want to verify our transactions without relying on a third party, and we use Bitcoin every day. It is also our bank, which is why we defend it tooth and nail and do not want it to change, because we do not want to risk losing our savings.

Here, most of those in favor of spam don't have "skin in the game."
