The idea that Bitcoin can be a store of value with a 1mb block size limit seems like nonsense to me. That's reversing cause and effect. Bitcoin gained value because it was useful, it didn't gain use because it had value - that can't be the case because it started out with a value of zero. So if Bitcoin is deliberately crippled so most people can't use it, it will also cease to have much (if any) value. You can't have one without the other. The best way to ensure Bitcoin is a solid store of value is to ensure it's widely accepted and used on an every day basis.

I fully agree with this.

On the other hand, if the blocksize is raised and it leads to centralization, Bitcoin as a decentralized currency will be destroyed forever.

Peter, I've struggled to try to understand you concerns but I still find your arguments convoluted and hard to follow. You want it to be possible to run a Bitcoin node on average hardware, but you don't want the people with average hardware to be able to use the network. How can that work? It's obvious that a blockchain recording all transactions is bound to be resource-intensive, but as far as I can see that's the very nature of a proof-of-work blockchain. Satoshi's idea was that such a resource-intensive system could be viable in the 21st century and he always presented Bitcoin as an accessible payment system, not as some sort of infrastructure for large financial services. And that idea is also what practically all of Bitcoin enthusiasts have been promoting during the last three years. I think I'm not the only one who's been telling his friends about how easy it is to get a Bitcoin wallet, and make payments to anyone around the world, and how this system could eventually be used to pay for a restaurant bill or to buy a book online. This is probably the idea that first attracted most of us to Bitcoin. If you think that such a thing is not possible and that Bitcoin can only survive as a low-volume network where payments are outrageosly expensive, well then that's like saying that you don't really believe in the original Bitcoin idea. You could be right, who knows, but keeping the block size limit is what effectively kills the Bitcoin dream, either by turning it into a specialist service used by a minority or, more likely, condemning it to irrelevance and oblivion. We need to find a compromise, and I think the sensible thing would be to agree to a higher block size limit. Those, like myself, who would remove the limit altogether will find a much higher limit more reasonable whereas those who are adamant that the limit is necessary could accept a value like 50 MB, and avoid crippling the system during the next few years.
