>Hence, I propose that instead of talking in bitcents we encourage the use of millicoins, microcoins, and nanocoins. That way the entire system relies on a single three-order grouping.

this is a very important discussion --

the root concept of 'bitcoin' is 'coin' - the monetary element, not bit - the generic data element --- using prefixes around 'coin' makes the most sense.

thankfully the international systems (SI) of units specifies twenty prefixes that go +/- 10 places --- so if 'bit' is the root coin value, you can express the following:

bitcoin = bcoin = 1 = a whole bitcoin

decicoin = dcoin = 0.1 = a tenth of a bitcoin

centicoin = ccoin = 0.01 = a hundredth of a bitcoin

millicoin = mcoin = 0.001 = a Thousandth of a bitcoin

microcoin = μcoin = 0.000001 = a Millionth of a bitcoin

nanocoin = ncoin = 0.000000001 = a Billionth of a bitcoin

now take that in the other direction and you can talk about equating bitcoins at higher scales as well - handy for summing up countries national debt for example:

decacoin = dacoin = 10 bitcoin = Ten bitcoins

hectocoin = hcoin = 100 bitcoin = 1 Hundred bitcoins

kilocoin = kcoin = 1,000 bitcoin = 1 Thousand bitcoins

megacoin = Mcoin = 1,000,000 bitcoin = 1 Million bitcoins

gigacoin = Gcoin = 1,000,000,000 bitcoin = 1 Billion bitcoins

standard calculators could be adapted like
