The core reason people say you should "never go full macro" is because diving into the hard data on this long term fiat debt cycle will only leave you feeling despondent and enraged by the self inflicted wounds of organized society. These emotions can easily tilt one into a permanent bearish stance on markets and risk taking when the optimal choice is to turn off your brain and long until the wheels literally come off the wagon in broad daylight, as they invariably always do. This is the juxtaposition of all market actors in a Fourth Turning. It's so incredibly fucking bearish that the only choice is to be bullish.
