Inflation is not a valid argument to support taking a high risk on a speculative asset. There are plenty of other assets to invest in to beat inflation such as real estate, inflation bonds, and stocks.
That's a nice list of risk free non speculative assets you got there.
Real estate is heavily taxed and risky since you often end up buying @ 10-20% more of the market price, it's illiquid and very costly to maintain
Inflation bonds don't protect against real inflation because they follow government numbers
Stocks can deliver well
