I'd be ok with 1 satoshi = $1
Seems to me, there's kind of a built-in limit for 1 satoshi to be only ever maximum equivalent of "One Cent", isn't there?
I mean, if a single SATOSHI is the current bare-minimum currency unit of the bitcoin protocol, and things will still need to still be priced in terms of the traditional, conventional "dollars and cents" model which ALL other currency all over the world uses (i.e. "$1.99" format)... well, a satoshi can really then only ever be a maximum replacement for a PENNY, right?
Otherwise, you'd have the problem of things only being able to be priced in terms of whole dollars (i.e. if a satoshi was $1) or even like maximum $1.95, $5.25, $999.85 etc. if a satoshi was equal to a nickel, if .05 is the lowest currency unit, in other words.
The US Gov't has wanted to get RID of the PENNY for a long time, since it costs more than a penny to MAKE a penny... but they've never been able to do it for, I think, this reason alone. Or am I missing something here? LOL
