Saying S2F model is "wrong/invalid/broken", means saying BTC price pumps after 2012, 2016, 2020 halvings (red arrows) are coincidences, random, unrelated to halvings.

Possible, but I disagree. IMO 21M cap, supply schedule, 4y halving cycle are fundamental to BTC price. IMO the halving will probably be at S2F model value $60k (dark blue) and BTC will pump after the halving (red), just like 2012, 2016, 2020 halvings.
