Let's talk about how things generally are. Would it be wrong to say that an increase in block size = require more resources = centralizing?
For in-depth discussion, i would say this statement has some inaccuracy.
For running a node on a dedicated computer like a Raspberry Pi, it will cost about $300 for all of the necessary hardware but if you have an old laptop or desktop computer sitting around, you can probably run a pruned node on that.
IMO they might as well as get 1TB SSD so they can get some speed boost (since old laptop/desktop usually use HDD) and could store whole blockchain.
For instance, I am planning on running a dedicated BTCPay server on a Ras Pi but I need to get it all set up before I can really be sure of how useful it is as an actual node.
It should be useful as actual node since BTCPay documentation show deployment example using Pi 4 4GB,
