Those are reasons why loses aren’t as big of a concern for rich people. Not why hedges are only for rich people.
The cost of a hedge is proportional to the assets being protected. If someone has say a $10,000 portfolio of stocks, and they think the market will crash in the next month or two, they could buy a protective option hedge for around $100. And if someone has a portfolio of $300 million, they could hedge for ~$3 million. Wealth is irrelevant.
Also hedges aren’t risky. They reduce risk. They’re insurance.
