Agreed on 1,2, and 4 especially - a complete red herring if countries are running deficits - it’s far more instructive to make Bitcoin ownership as easy as possible for every individual who is not running a deficit themselves.
On Bitcoin Treasury Companies though - I think it pays to think long term. Corporations and potential investment in them will always exist. It’s only natural that investments in these companies pop up as an option (essentially priced in Bitcoin) relative to just saving in Bitcoin. You may end up with more or less Bitcoin than you invest - like any investment - buyer beware of course. But it’s a pretty natural state of things that these will pop up and try and acquire Bitcoin - especially when tapping into other capital pools (fixed income etc) that can’t otherwise access it, as Saylor is doing.
