Substantial doesn't mean outrageous, dumb and ridiculous as what you are suggesting. FF11 had xp loss to the point you can de-level. Weakness had a much bigger timer and much more detrimental effect that would stack every death. Dying was horrible and made every tough fight something to sweat over. It made people into better players.

What everyone here is asking for is making the game stupidly and boringly simple, this food persistence request is another layer of a pointless game mechanic to cater to those who want the reward without the risk or work.
