If your money is locked up in stocks, then it's locked away. That was the whole point. It doesn't matter if the money is tied up in stocks, gold, or bitcoin, it's the same thing as keeping it under your mattress. Billionaires not only have immeasurable wealth in assets, but they also have immeasurable wealth from profits generated by underpaying their workers and squeezing every ounce of energy out of them so they can't actually enjoy a meaningful life. Billionaires keep their wealth locked away in different places, but it's still all locked away and inaccessible from the people who actually earned it. So yes, I've thought a lot about this statement.
