All of that stuff is really relative. If you put more money into fancy setups and expensive equipment, of course it's not going to be cost effective. Especially in the first year - the honey example is a little misleading, because of course the first batch of honey is going to be expensive - you have the capital expensive of buying the hives and everything in the first year. The second year's batch of honey is only going to be a fraction of the cost though, since your inputs are minimal. Same with the goats and chickens.
And she'll make hotdog buns but not hamburger buns? It sounds like she doesn't know how to make bread, if she can't make a roll good enough to stand up to a juicy burger. And I don't know about you guys, but my burgers are not "oozing" juice. They're juicy, but not oozing the stuff! That would be gross.
Bacon - she says home made costs $3.50 a pound and store bought cost $5.00, then refers to home made as expensive? And I make bacon all the time - it doesn't really take up that much room in the fridge at all.
Pizza - does not require twenty four hours to make a crust! I have an excellent yeast dough recipe that's ready to go in a few hours and is amazing.
I don't know - articles like this one kind of make me mad. This stuff is so subjective, and articles like this can really turn people off to trying to do more of their own food at home. People really need to cost it out for themselves - an article showing how to do that would be more useful. And it bothers me when articles like this allude to the fact that you're wasting money because you're not getting paid for the time spent to do something - home economy doesn't necessarily work like that! Especially not if you enjoy doing it and it's not some drudgery that you'd need to earn a monetary wage for.
