They won't listen to
the reality until it bankrupts them.
You're probably wasting your time trying to educate them.
It seems quite obvious to me we are (quickly) headed for a situation of equilibrium in regard to mutually assured destruction where all parties will simply veto any proposal that radically changes the system and specifically the IMPLIED value proposition.
You and everyone else here seems to have the attitude that such an equilibrium will destroy the system, based on the tacit assumption that bitcoin's value comes from its transactions per second, when the only possible founded argument is that bitcoin's value comes from its gold-like characteristics that are related to the reason we value gold so highly.
We don't value gold for its transactability, we have many other systems that are far better for this. It's valuable for a wholly different reason and so is bitcoin.
There is no scientifically based argument that suggests otherwise and if there is then bring it forth.
