I think this touches upon an even bigger problem in the Bitcoin community. Very few people actually know what they want other than the price to go up. And those who do are all at odds with eachother because Bitcoin can't do everything at once.

The very people who want the value to go up will keep the Bitcoin alive. It is too early to proclaim it dead.

  LOL, that works until it doesn't. There's a name for that sort of financial scheme...

I have no history with Bitcoin, but if people want the value of Bitcoin to go up I think it'd behoove them to make Bitcoin useful to people as a solution to a problem. I'm not sure the idea of a decentralized reserve currency with unknown/random time-to-liquidity is a very useful solution to any problem. Bitcoin obviously has value right now as demonstrated by the fact that people can go out and exchange coins for things people regard as valuable, but current value is not a perfect indicator of future value and I'd argue that the current value is at least somewhat predicated on the belief that Bitcoin will eventually become a useful replacement for today's highly-liquid real-time transactional currencies. I am probably naive, but can't a solution be found by simply increasing the block chain size and then creating software that makes the verification of transactions more distributed by making the process more fine grained in terms of CPU and memory resources? In other words, split current "nodes" into a more fine grained distributed virtual node that low end computers can run?

  It isn't about computational difficulty. Larger block sizes simply mean larger blockchains and more network use to transfer them around. The verification of transactions in bitcoin is central to its protocol. Its the whole reason its novel and relevant. You would have to change the proof of work system from sha256 hashing to something else to make it anything but optimal for computation on specialized ASIC hardware. If you do that, now you have another cryptocurrency - litecoin, peercoin, etc. And when you use a hashing algorithm meant to be hard for general computers (cpu or gpu) to do, and can manufacture hardware that does them much more efficiently, you end up where we are now where big miners and a handful of people represent most of bitcoins mining power.

    No matter what crazy optimized-for-decentralization algorithm you come up with to mine cryptocurrency, large investors are going to buy a ton of it and put it in datacenters in China. Newbies and people invested in alternative attempts at Proof of Work often complain about this longstanding issue while utterly failing to solve it themselves.

      Is it an issue? Of course you could spend millions to buy mining hardware. The issue in bitcoin is more that you spend millions on novel mining hardware nobody else has. If your hashing function is CPU or GPU friendly, suddenly everyone in the economy has hardware capable of potentially mining your crytocurrency. The problem with bitcoin is that those hundred million dollar datacenters are the only places top of the line SHA256 hashing hardware is found. If they were just GPU cluster datacenters, despite their scale, they still would not compete with the distributed power of millions of home users desktops to as much a ludicrous degree as modern ASIC miners are in the bitcoin space.

Do you suggest efficiencies of scale don't apply to GPU clusters in datacenters, or CPU clusters in datacenters? As it pertains to mining centralization, do you suggest efficiences of scale only apply to sha256 ASICs? The idea that this can be "solved" with clever code is utterly naive. The bottom line is investors in any cryptocurrency, regardless of its hashing algo, will buy up the majority of the hashing rate with high efficiency rigs in well-connected datacenters with low priced electricity. Tell me how to fix that with code. You can't do it - although I've certainly seen more than my fair share of altcoin investors try in vain to do just that.
