Is it really that baffling? People expect their bread to last more than two days, and it has to stay on the supermarket shelves longer than that. Of course you can cook your own bread and eat it quickly, but it's not very practical for a lot of people.
Is it really lazy to not be able to go the the store every couple of days? Seems like a lot of work and fuel consumption to avoid some preservatives, especially considering that there's no evidence of them being harmful.
