It is nice to see that some real philosophers have joined the discussion, I am a philosopher as well. I have constructed a simple argument of my own, you are welcome to try and rebuttal. There has been a lack of rational responses to my arguments so far, and far to much ad hominem and hyperbole. I believe that good philosophy should be simple.

To put it simply, if we do not increase the block size it will be more expensive and less people will be able to use it, that is to transact on the main chain directly, and instead we will be "forced" to us 3rd party payment processors.

However if we increase the block size then it will be less expensive and more people will be able to use it. Even if full nodes will only be able to be hosted on powerful computers, since miners do not run full nodes, the pools do.

Considering that these would be the most likely outcomes with increased adoption, to me it seems clear that increasing the block size would lead to more decentralization as a whole compared to keeping the restriction in place.

I can go into much more detail of course but I would like to keep it simple in the interest of constructive argument.
