FWIW I don't think you should be attracting so many downvotes, because while your point of view is apparently unpopular, you do seem to be arguing it in good faith. (Although for what it's worth, bringing yachts and day trading into it seems a bit of a strawman given the conversation was originally about main street businesses.)

I think my answer to another comment of yours above basically outlines what I mean by creating value. The example of the successful restaurant choosing between building up cash and opening a second location. Basically if a business has sufficient profits that they're able to store up a significant cash buffer, it's because they're making something that people are willing to pay for. (Or they're particularly good at regulatory capture or rent seeking or something, sure, but for the most part there is a correlation between earning money and providing something of worth.) Businesses that make popular products and provide popular services—things that people like and are willing to pay for—make more money than those that don't. And these things that people want and are willing to pay for, by definition, have value. So rather than sitting on cash, when possible we would like these businesses to do more of what they're doing.

As another example, say you start a tractor company. You really understand what makes a good tractor, and your tractors are widely considered to be the best available. The only problem is, you only have one small factory, and can only produce a small number of them. You turn a profit on each one, and you want to be responsible, so you're saving most of that profit in case of a natural disaster or other calamitous event. It takes around 10 years to save up enough that you could keep all your staff on, your equipment in good shape, and your rent paid for a year, but you manage it. Unfortunately in the meantime, most of the farmers in the worth need to make do with shittier tractors, because instead of growing your business you're trying to build up a bunch of cash. Wouldn't it be better if you reinvested as much as possible into the business—borrowing even—to scale up your production as quickly as possible? That way more people get to benefit from your awesome tractors and everyone is better off. If a pandemic happens, the government helps you get through, so once it's over you can go back to making and selling these machines that are making farms more productive. And all the added production from that reinvestment is of course also creating jobs, paying more in taxes, and earning you more income as well.

Now sure, your direct competitors won't love your selling a better tractor, but if we scale the example out to the whole economy, the more successful companies are making and doing successful things, the more actual wealth is created for society. And of course, not all companies make useful things, and the things people spend money on aren't always objectively valuable either. But in aggregate it's pretty clear that value is created. Just look at the quality of life people enjoy now compared to say a century ago. There are serious problems (like climate change) that we need to tackle—I'm not at all arguing for unregulated capitalism as a panacea. But I think it's objectively true that if all companies strove to each build large nest-eggs to weather events like this one, far less wealth (meaning tangible stuff of value) would be created than is otherwise the case.
