LOL you likely are a renter.

I'm a renter and i still think real estate is a better bet.
Better to have something that is "mine" rather than face the threat of eviction if my landlord decides to sell up.
Its never a good idea to be beholden to someone else.
As for the garden thing, I'd rather have something to defend that could feed me, and give me something to trade than a bucket of beans I can only do so much with.
Get a 5 gallon bucket and fill it up with .22LR ammunition, drop in a couple of oxygen absorbers and then close the lid and put it in your closet until you need "cash" to barter with. Bullets, beans and butt wipes will always be in demand. ;)
You only have a plan for failure and hence it will fail.
