On the commandment of appointing a king in our time

Further to what is said here. Do you think that in that state of law we would be obligated to appoint a king? There is a minority of opinions that appointing a king is an option and not an obligation (and this is also the plain meaning of the verse, and this is implied by the Book of Samuel). The verse also states, “And you said, ‘I will appoint a king over me like all the nations that are around me.'” Ostensibly, it can be interpreted that the commandment to appoint a king applies only when the custom of the nations is to appoint a king, but in our day, when the custom is not like that, it is possible that the obligation is null and void, or it can also be interpreted that the obligation is to regulate “kingdom” as is customary among the nations, and in our day, the “kingdom” that is customary is a democracy.
