Your whole argument is a straw man though. I don't think anybody is suggesting that the only type of businesses are VC backed businesses.

Starting a high-growth startup is a risky, stressful endeavor. If you want to start a business that is not high-growth that is bootstrapped and grows slow but steady, great! That can result in an awesome financial outcome for you personally. Some people enjoy chasing hyper-growth and the risks that go with it, that doesn't make the OPs post wrong, it just means it applies to a different type of business and a different type of entrepreneur.
