The idea that a country needs (~~to exist~~) to be ruled by a single individual is completely unfounded, and perpetuated by people who are either fools or foolish enough to think they have a shot at the throne. Early on, there were proposals for the USA to have a king, a president, and many other ideas including no executive branch or having a tribunal. I could see a good case for splitting the executive across 3 persons with equal and asymmetrical powers.

Assuming you do a ranked choice vote for all 3 at once (or 1 at a time in rotation, like Senators) it should be extremely difficult to compromise the office by, say, buying one deeply indebted former TV host and running them for president.
