Of course the market forces that are naturally present in a purely capitalist economy require there to be workers and employers.

In the scenario that you described, are you suggesting that instead of 10,000 people working at TSMC, we’d have 10,000 semiconductor factories that are built, operated, maintained, cleaned, and supplied by 10,000 individual people?

We can use an even simpler scenario. I believe that you’re suggesting that instead of the way that the food service sector currently works, it would instead be possible under capitalism for all food-service workers to individually sell served food to customers, presumably from their own kitchens.

In that scenario, what happens when Bob McDonald offers 10 of his friends to come work in his kitchen for an hourly wage, and they’re able to produce better food (due to specialization) for a lower price (due to lower overhead per worker)? Bob (and the countless other people who will undoubtedly copy his success) will outcompete the slower, more expensive kitchens. Individually owned and operated kitchens will be driven out of business. Then small, 10-person kitchens will start to struggle against larger kitchens and chain kitchens that have been able to spread the costs over multiple locations.

Before long, it will be impossible for a Sally Jones to open and run her own kitchen alone. In order to just break even, Sally’s prices would be significantly higher than the food sold at Bob McDonald’s chain. The cost of her premises will be higher relative to the amount of food she can produce on her own, the cost of the ingredients themselves will be higher because of bulk purchase prices vs retail, the cost of preparing the food will be higher because she doesn’t have access to an industrial onion chopper that can peel and chop a 50lb bag of onions in 30 seconds.

Market forces make it impossible for an individual to compete, due to the economies of scale. This is the same reason that over time, corporations under capitalism merge and restructure as they tend toward a monopoly.

I might be totally misunderstanding what you’re suggesting. If what you meant was that instead of the 10,000 TSMC workers each having their own chip foundries, that they’d all still work at the same factory, but that they’d have collectively funded and built the factory, and that they each individually work for themselves at the factory and share in the money they get from selling chips, then I’d agree that that’s an awesome system. It’s still not really possible under capitalism, because if that’s what you’re describing, it is actually called socialism.
