Actually this is the real solution to invasive governments.
You can trust what you own.
And ownership is not linked only to possession, as compromised systems show.
You need to own it both physically and on operation / management level so that nobody can interfere (hack / compromise) .
Owning cloud VM is ok but pushes more investment on the operation ownership than with physical systems: ie what you save on price you must reinvest in crypto layers and detection systems.
