You are one person. What happens when you are away, ill, or under a bus?
The fair objection, and the reason everything is arranged the way it is. Every domain, licence and account is in your name. You hold every password. Each job ends with a written page covering what is plugged into what.
So if I vanish tomorrow, any competent person can pick your setup up and carry on — which is more than can be said for a setup only a departing provider ever understood. For planned time away I tell you in advance. For anything genuinely urgent while I am unreachable, that documentation is exactly what lets somebody else help you today instead of next week.
