No, this is not the way. Lone sacrificial actors hurting wealthy people wouldn't work - they've got a whole system lined up to keep their generational wealth and power and it is extremely robust and every time you got rid of a billionaire you would get a handful more billionaires popping up where they were. Not only that, it would embolden reaction. You thought the BLM protests caused a violent police reaction? Assassinate one billionaire and just watch what happens. The reactionary machine would go ballistic. Maybe you want that, but that's called accelerationism and it has never once worked to achieve anything good. Similarly the act of lashing out as a lone wolf has a name: revolutionary adventurism. It also doesn't work.

The actual method that can work is prefiguration, building the new society in the shell of the old. We make the world better for ourselves and our neighbours right here and now and we don't wait for permission from conservative and reactionary systems. We make them irrelevant to our projects.

When the CNT-FAI dispossessed the wealthy of their private property, they didn't purge them. They offered them a place in their new society. Many took them up on the offer and admitted it was a good life. That's a much more profound victory than just ganking someone.
