You could make the exact same argument about wedding rings, really. What are they if not a symbol of essentially "owning" the sole rights to another person's intimacy and love?But MC is the Master of the girls. The way to officially get in his harem is him collaring the girls and they have to wear it everywhere both private and public. It is just symbolism that these girls are now his 'property'.
I don't recall the MC ever making any kind of demand like that. I remember him making a point of how important it is to him, but admittedly I'm not 100% certain. It was a while ago I played through the earlier parts of the story.Hell He even says that he is going to continue to see different girls and continue to expand his harem but the girls are forbidden to look at another man except him.
I won't deny that I too find the MC to be uncommonly (and definitely refreshingly) candid about his wishes, but I feel it's worth pointing out that there's a huge leap from being controlling and demanding, to just being generally dominant. And for whatever it's worth, the MC in this game is definitely more leaning towards the latter.I find it refreshing the mc is straight up declaring he is making a harem instead of dilly-dallying it until the end like other harem vns
