Maybe not, but most of the world HATES decimals in prices. Decimals confuse people. Would you like to see a cup of coffee cost 2 milliBits or 0.002 bitcoins? It's much easier to understand whole numbers. Also, many people think 1000 $ /bitcoin unit is too expensive. I try to tell them they can buy fractions of a bitcoin, but they hate that idea. People don't like dealing with fractions. It's basic psychology.
