People don't want to feel like they own a fraction of something. I'm all for the move to Milli even if I'm not 100% fond of the name.
People should get used to it and calculate more. People are buing gold even if they own "fraction of kilogram".
This is like stupid posting "price per kg" on the packages of different weighted goods. Anyone should be able to do this math by himself and compare.
if you want widespread adoption you don't make people calculate more.. that's a poor business plan and a narrow minded approach.. you have to make them calculate less..
Besides, comparing with gold makes no sense... people don't use gold to buy coffee
This.
Yes, those who can do math will do it, but people do not want to do math and many people think better in whole units. The difference is marketing vs technical arguments about math and using a calculator. It is a lot easier for the majority of people to miss a zero when entering 0.00005 and 0.000005.
But, as said above there is no standards body to impose standard units. Setting a date in the future, and convincing a majority of large bitcoin exchanges/payment processors/web sites/developers etc to switch the default view to something else on that day is about the best you can hope for.
