Financial markets in general do not demand this. As someone else said, the return expected is just a basic risk-free rate plus some compensation for the added risk of owning equities instead of treasuries, which isn't nothing but it doesn't mean you need to double in size every year indefinitely. The problem for FAANGs and Tesla is their valuation was predicated on indefinite rapid growth. Once you have that valuation, the only way to keep it is to actually grow at the rate the valuation priced in. If you don't, the price will drop and all of the various directors and high-level employees whose compensation is largely in the already heavily-priced stock will lose a lot of net worth. This isn't a problem for all publicly-traded companies. It's a problem specific to a very small number of extremely highly-valued companies whose value was based upon the expectation that they would grow very rapidly. Venture capital is another matter entirely. Being far riskier than owning publicly-traded equity shares, they do demand outsized growth from every investment. But venture capital is hardly ubiquitous. Outside of software devs, all small business owners I've ever known would not have even tried to consider it. If they need money, they ask their parents or a bank.
