Of course I disagree with it, otherwise I wouldn't own any Bitcoin.  The marginal cost over time of Bitcoin shows an ever increasing percent being energy costs.  This means sha256d will likely be commoditized.  There is no Chinese monopoly after that happens.  Of course, China being the top producers of Bitcoin isn't even a Bitcoin problem in the first place.  It's a symptom of China controlling manufacturing for everything on earth as corporations use their slaves for global labor arbitrage.

This problem will also cease to exist, either through tariffs or war.  US has already placed huge tariffs on China steel.  Next, every country will place huge tariffs on everything else coming out of China.  It's likely mining will be done only in situations where the waste heat is actually useful to drive some other function as well, or power is very cheap from things like hydro dams.  If sha256d is commoditized, it's not just a single dam in China that benefits.  Bitcoin is already at rock bottom for decentralization and can only get better from this point on.  Claiming it gets worse from here makes zero sense when we know sha256d becoming commoditized can only make it better.  It can't get worse than now!  You've already hit rock bottom.
