This appeals to me. Why not believe that convention, society, rules, regulations, customs, taboos, all stand powerless and in awe of love?

Because they don't.

People who fall in love with other people and, more importantly, stay in love with them, don't exist in a social void. They are products of convention, subjects of social custom.

We might like to delude ourselves into thinking that we are different - hey, I myself could give you a dissertation about why my marriage is a bold cry in the face of conformity - but the truth is, we choose the people we love with the same engrained tools that we've been indoctrinated into using from the day we were born.
