Well even though the planet and space theoretically have a glutton of spare resources just waiting to be gathered and used... it still takes time and you have to use the existing resources to gather it.
So every moment in time, there's only so much resource available vs money to pay for it and move it around to do things. There's only so much time in a day for people with money to spend that money on doing things including getting more resources out of the planet.
Billionaires have enough that they can gather whatever resources they want, but their actions carry heavy weight. They're still only so much of a person so that limits how much resource they can allot in the 24hr day cycle to people who utilize that $ to do useful things.
That means billionaires are incentivized to funnel money into more singular focuses or create companies that spend their money for them. Which creates complications on where and when those people spend the resources.
So eventually you end up with a situation where too few people have too many resources sitting around collecting dust, without being recirculated through the economic arteries of the countries they siphoned that money out of.
Resources aren't being gathered fast enough to offset this, so there are large periods of times where there's a backlog of capital not reentering the system.
Eventually the system begins to buckle because at some level it relies on that capital up top coming back down. Too many billionaires means not enough capital is coming back down into the system they got it from.
My politics are spherical btw, I stopped seeing political sports teams ages ago, but still recognize they exist for multiple reasons, so I dunno what the "left" argument is, but I wager they might agree with a couple points I've made, though they'd have different ideas of what to do WITH that info.
Make of it what you will. It's a real problem but other than taking back some of their wealth, there's no real pragmatic solution.
