If you wanted to base the entirety of the world economy on baseball cards, I'd say that you're crazy. The fact that you put company names on them instead and don't make them physical cards doesn't make it less crazy.
You seem to ignore that.
The economy is not based on the stocks, but on the value the underlying companies produce. E.g. Tesla makes cars, Google runs a search engine. Such companies impact the real world - Baseball cards collect dust.
It’s a broken comparison.
