Giving first-line managers the freedom to hire and fire would be a stupid way to manage an organization. Most of those managers lack the experience, competence, and perspective to make that type of decision effectively. Which is why competent organizations support them with a surrounding structure of corporate policies, senior management, and human resources to (hopefully) prevent first-line managers from making too many mistakes.

If you don't have competent enough first-line managers to decide who they can effectively work with, your whole org will become a micromanagement hell. Which breaks down if you try to do it remotely.

Of course the implementation of hire/fire does not mean that the first line manager does the interview alone, without any help, supervision, oversight and support from middle management and HR. But if you have no say in who you manage, who you work with, it'll be very hard to get work done.

And in my experience this usually already happens informally anyway.
