You're welcome. It's why I wanted to promote your post even at this late date.
Another reason to grow your own food as a personal finance strategy is that the food itself is an asset that can be sold. Old-school people buy precious metals for use as money, and many crypto people prefer decentralized digital currency over precious metals.
