The intent is to criminalise cash usage, starting with the higher value notes. Cash is a problem as the merest hint of banking system insolvency means lines out the door. Removing higher value notes from circulation is part of the strategy of both maintaining the viability of a rigged system, and pushing more people into it against their will.
There can be no bank runs if there is no cash to withdraw. Electronic transfers can be blocked. Banking holidays weren't originally just a day off. They were a day to restructure debt and hide the skeletons whilst peoples lives and savings hung in the balance.
And as for cash. Well, clearly anyone who uses it must be portrayed as a criminal, part of the black economy, and not paying their share of ransom money to the govt of the day. Hence the vilification.
