And did not the Lord say that these fasts were to "release the captive" and "deal your bread to the hungry"? Cursed communist, private property hater He! (/sarcasm, in case anyone misses it)
(I know you're not dissing God) ;)
Seriously though, what you propose is that therefore all private ownership is sin, since we should give whatever we have to the neediest.
I don't think He wants that.
Further, if it is true, as I believe it is, that price gouging saves lives, then my way is doing the greatest good, and ensuring the widest dispersement of property to those in need, and ensuring against hoarding.

The only way you can insure that your bread goes to hungriest is to sell to those who are willing to pay the most.
