LOL!!! Sorry, just finished reading your "whys" for staying home. To the person on the outside looking In at the SAHM this sounds like the ideal life. I hate to burst your bubble but it won't be THAT easy.
I worked for 12 years in the corporate world; suits, pantyhose, high heels, and make-up every day. Be at work before the sun came up and left long after it went down. Drove 1 1/2 hours both ways.
What happned to change that? My DH and I got custody of his two children (then 9 and 10) and one of us needed to stay home. I gladly volunteered for all the reasons you mentioned. Honey, I found myself MORE busy and MORE tired (which made me more cranky) than I was working 80 hour weeks in the corporate arena.
Be careful what you wish for... you just might get it (along with some things you didn't realized came with it).
