Imagine being the copy that has to work while one does the family and one is traveling. The ethics of making a copy of myself that is for all purposes a slave would be really weird. Enslaving copies of myself, what a concept. Oh, also one needs to be kept on away for organ needs as I age or get hurt and one with a master copy in case the main "I" dies unexpectedly. yikes
The second season of Invincible touches on this with the Mauler Twins (which aren't actually twins, but instead one guy who clones himself and copies over his brain so there is always two of him around):

Usually when they make a clone they can't tell which of them is the original and which is the copy (even though they ought to be able to know by remembering which medical bed the original was lying in, but never mind that), so they work together as equals. However, one time they make a copy after having suffered a disfiguring injury, so they know which one is the original and he lords it over the copy until the copy gets fed up and kills him. The copy sums it up as "sometimes things are the way they are for a good fucking reason."
That's assuming your copies have individualism. Where I feel my copies would believe in the greater good. Almost all know the role they play to make my true version incredible.
And knowing myself well, one would absolutely rebel to have empathy for the "worker" versions, and find a middle ground. Maybe 4-day weekends and vacations once a year.
Maybe your awareness splits with each copy, so you go from an "I" to a "we." No such thing as a "master" copy then, just different organs of the same meta entity
