On Linux, I do not install sudo, because I do not need very often to become root, and when I need that I usually want to do multiple operations. I believe that "sudo" is useful only on multi-user computers (including company-owned and company-managed computers), where the administrator may want to give to some users the power to do only a restricted set of privileged operations. I always use a different user account than root, mainly not for security, but to avoid any accidental mistakes, when I could delete or overwrite other files than intended. I believe that this is a good enough reason to justify the need to type infrequently a password in order to change roles.
