Well, there’s nothing stopping subdivision of a currency by any means available. Bad money drives out good as well, so in practice, people cash in bitcoin and pay with dollars in order to pay small fraction of what 1 bitcoin is worth. In theory, a “sub coin” could handle this but I guess it hasn’t been desired enough for anyone to bother specializing in it. All I am saying is theoretically there is no issue. Oh and others mention subdividing bitcoin directly so there is that.
