The idea that it is proper to adjust the rate of monetary creation based on the market is suspect. It can't create wealth, it can create confusion and is looks suspiciously like a distortion that results in asset owners becoming wealthy at the expense of someone else. Asset prices appear to inflate more in line with the M2 - somewhat faster than the CPI, suggesting that asset owners are getting more benefits from this policy than anyone else. I don't see why they need an extra boost given that they already own productive assets.
Basically; at the moment the system is designed to penalise anyone who tries to preserve wealth in actual cash and as collateral damage prices keep eternally climbing. Neither of those things is helpful and if anything it just makes it harder for people to make rational decisions. It is confusing policy with no theoretical upside that has been drawn to my attention.
