My "FTFY" is correct assuming BTC purchasing power = OJ's nutritious value.
You won't increase market cap by x1000 by introducing millisatoshis.
I do understand where you're coming from and you're not wrong saying that it's essentially creating x1000 more bitcoins and changing definition of what "bitcoin" is, but that would have zero effect on the price, other than maybe caused by psychological discomfort and few bad press hits (I. Kaminska from FT would be all over it).
It's definitely not the same as i.e. changing 21m cap to 100m etc. It's essentially the same as dividing shares of a company, i.e. from 10 to 10,000, it won't have any effect on % holding of each shareholder and will have no effect on the value of share capital. So what's the issue?
