All reactions are taking this comment seriously, but I think it can be also read as "money equals power" (which I strongly believe - there's some power without money and sometimes money without power, but mostly those two are fungible) - and then pointing to the futility of getting money out of politics, since politics is about power.

But really what people mean is "prevent paid political advertisement of all kinds", which seems about as hard as "get rid of all kinds of advertisement" - at some point, you're back to power, communication, attention.

Hard problems. Probably there's a reason all ancient democracies did not survive.
