BitsharesX (in at least most of its quickly-mutating versions), is unlikely to gain widespread acceptance for several reasons, the chief of which is DPoS, which makes highly flawed assumptions about human nature, is explicitly plutocratic (and not capitalist), has market-design-features which sap needed liquidity, employs Soviet-style price fixing (which retards the flourishing of the crucial BitUSD), doesn’t scale (technically it may scale…recall this is a micro-econ blog), and is simply/cheaply attacked (or, at least, completely re-centralized) by finding/threatening/murdering 76% of the “delegates”.
I think our market design is likely not optimal and some liquidity will be lost to this (and we could probably do without feeds with a better design -- not that they're really an issue for anyone other than delegates), but the rest of the points just sound like they're from someone who hasn't thought very deeply about these things.
It's really quite trivial and obvious that DPOS just organizes the centralization that would be present in any system rather than allowing it to form in an ad hoc and likely less secure fashion.
