People often confuse strategy and tactics. In chess, strategy is over the course of the game, while tactics are temporal, clever moments. Like in chess, like in poker, like in life - if you only ever play with a static technique, you are mistaking tactics for strategy.
A supposed reliance on an issuance schedule admist an ever-changing macro economic environment? I think the 4 year cycle was a blip. A clever technique to use in Bitcoin's adolescence, but not something you should expect to be constant as it grows in adoption. It's myopic to view the halving cycle as the holy grail of indicators. Tactics are tools, not lifestyles.
This is an emergent trait of time in complex systems. Science, understandings and entropy all grow in nuance and complexity over time. Generalizations can only hold so long. Like a reptile must molt to grow, so too must the strategic thinker molt their past understandings in order to progress.
