I don’t want to keep my savings in currency because I fear inflation. I don’t want to buy Gold because I fear there is tons more Gold on Mars, making precious metals less rare than they are valued now.
I don’t want to invest in stocks or bonds because I don’t trust corporations or the faith and credit of governments these days, eh
Buying books will help to an extent, but there becomes wear and tear and also when the economy is in dire straits the price of books drops reverse to inflation.
If I buy real estate, it may become worthless if one day people live in space and there’s no demand for land on earth.
BUT….if I plant a maple tree in Canada. Then 40 years I watch it grow and then MAPLE SYRUP every spring forever…..and there we have it, I sell the maple syrup for a living into my retirement 🙂
