I guess I'll be the one to say it. In the words of the late George Carlin "Pancakes. Griddle cakes. Hotcakes. Flapjacks. Why are there four names for grilled batter and one word for love?"
The ancient Greeks subdivided what we call love into several different categories with specific words for each; unfortunately, I don't know what they are, so we'll have to make do with English. What I feel for my parents was not the same as what I feel for my sisters, which is different from what I feel for my various dogs, or my friends, or a particular sandwich called "the Balboa" at my unfortunately-no-longer-local sandwich shop. All those feelings are real, and all often subsumed into a single word in English, which has more words than any other language humanity has yet devised. How the heck did THAT happen?
I don't think that's what you're asking about, though; you're asking about romantic partnerships (I think). One can certainly have those feelings of affection and loyalty towards a person in that type of relationship; I imagine it helps if you do. Much of the rhetoric around "love" in the romantic sense holds that once the infatuation and lust passes, you move on to something deeper, something somehow nobler, something that sounds, to my perspective at least, exactly like the loyalty and affection I mentioned before- nothing that you couldn't, in theory, already have had.
Am I mistaken? I don't know. I hope so, that there's more to it than I suspect. I've had too many betrayals on too deep a level to extend that level of trust (sometimes that Aspergian long-term memory is truly a curse), so finding out falls to other people. I feel, however, that the real con isn't Hollywood saying that it's all lust and infatuation, but the self-appointed wise-men (and -women) saying that lust and infatuation are somehow bad. Is it good to have more? Sure. But count the cost. I believe a lot more suffering is caused by people wanting "something more" in a romance's emotional terms than in its sexual ones.
I also believe I want one of those Baboas now. Stupid lockdown.
