I fail to see how, given the system we currently have is called capitalism and given that this content is contemporary. The behavior is analogous to behaviors that would have potentially been possible under aristocracy, but it's pretty clearly a phenomenon of late capitalism unless you take a completely ahistorical view of existence. Ideas with historicity have history, they aren't fixed idealist definitions...Mr Beast is functioning in a system we call capitalism because of the general rules it follows and taking actions enabled by the flow of wealth in such a system.
Capitalism isn't just some abstract Platonic definition, we are living it, it evolves in time. Just as the feudalism before it was a lived system that evolved in time, that eventually collapsed, giving way to a new mode (capitalism), the same will happen under this economic system.
