a 6102 attack is not needed in the modern day over financialized etf crazed system because the banks are the government and the therefore 6102 has already occurred on the day that etfs are approved
gov just wants the taxes to pay off it's debt (or to allow for future borrowing) it doesn't need the bitcoin
all the US gov needs to do these days is attract capital into its country and then never let it leave.
there is no need for overt acts of confiscation
if they ever need to transact for oil or anything scarce in bitcoin they just need to control the on-ramp into bitcoin so you must use dollars to buy bitcoin
the bitcoin-dollar system is the new petro-dollar system
that is why they are so heavy handed with offshore exchanges
this proves my point. the goal is on and off ramp total control and/or extreme friction.
welcome to the bitcoin-dollar system.
goodbye petro-dollar system. 
The more people that accept and transact in bitcoin amongst one another the less this law will matter. If eventually you can just circulate within the bitcoin economy the irs will have to eat shit.
