Bitcoin is smashing all other forms of store of value and has been since its inception. When you point this out to the masses however, it turns out that even 45% IRR is not enough for people to take time to understand it.
The post is calling out that this is a concern because short term thinking is what 99% of the World uses for decision making. And that's not good for the long term prospects of store of value because Bitcoin is in fact losing and will likely lose the medium of exchange war to Visa, Tether, Stripe or whatever fiat extension the fiat kings prefer.
So iff 99% of the World only thinks in terms of the medium of exchange characteristic of money, which the last 16 years has proven, then eventually store of value hits the addressable market wall while centralized terminals push out Bitcoin transactions for something they prefer. If you don't win the critical mass race for Bitcoin to become a MoE, you must discount its value as money and therefore discount it as a store of value because there is simply more demand and more valuable money than Bitcoin for 99% of the World more interested in medium of exchange properties than store of value.
This is not a controversial take, it's simply pointing out what people use money for and 99% don't care about store of value if they are short term thinkers. They care about Medium of Exchange.
