I think this is one thing that older generations have context for that younger ones (before becoming parents) can simply be unaware of. I know, I became a parent within the last year and it has changed my thinking on many things.
Even if we tried to live a life without love, I don't know that it's possible. Individually perhaps, but not as a strategy to have the human species continue to go forward. Empathy is something that healthy brains do naturally, and is really useful to keep a tribe or a society going (could even be required). This goes back to keeping children alive; when parents can't or won't, the tribe steps in.
Perhaps the modern world can make love obsolete; I hope that isn't the case. I think our minds have evolved to live in a pre-modern era. Until we fundamentally change our biochemistry, I'm pretty sure we'll have to make do with it (along with it being a hindrance).
