Sorry, I can't accept the reasoning there. Julien is a great player and I'm excited we have him, but Luzardo easily has 3 times the value. Top of the rotation starters cost controlled for 3 years are like unicorns. It will (and should) hurt to acquire them. That doesn't mean it sets us back, like some have suggested, it means we leverage areas of strength (INF, OF depth and farm system) to completely set up our rotation for years to come.
And, yes, maybe being friends with Lopez isn't all that meaningful. But being left handed certainly is.
