Mod up please. Natural people (human beings) are not 'people' in the legal sense. Legally, a 'person' is an entity that can have rights and responsibilities ascribed to it (as far as I understand, imagine the slave trade, slaves weren't 'people' - they had no rights - though I may be wrong).
Also, a human being cannot do business with legal fiction (a coporation) so your 'Person' (a legal entity created upon certification of birth) is there for that reason. A strawman used to enter into the commercial world.
Everything's a company of some description; countries, states, ministries, councils. The entire subject is a pretty eye-opening rabbit hole.
