now you are just playing dumb. we both know what would happen if lots of people try to take possession of UTXOs at the same time. please don't try that stupid crap on me. and I'm not talking about the gold confiscations either but you can pretend I am if it helps you cope with bitcoin's excessive dependence on custodians.

Why would I take possession of a utxo if my BTC is in cold storage?
These arguments are too speculative. I'm not convinced that batched transactions can't scale the thing, and I'm not convinced that transaction fees will be too high, and I'm not convinced that there will be such a huge need for block space. Fees can go lower than 1 sat/vbyte. The blocks are probably already too big, IMO. It seems darn near perfect... Longer block intervals would be nice, but I don't see anyone raising that issue yet. Focus on the privacy issue - maximize the good that comes from the criticism. Imagine if we get this perfect scenario, where the institutions get so married to Bitcoin that they can't back out when we suddenly all start running a version that has getter privacy. Push for that...
