In Bitcoin investment there's no such words as "impossibilities". Market rise and fall daily likewise bitcoin. Some things that people don't understand is that the principles of bitcoin innovation cannot allow bitcoin go down below some certain prices. As it stands now, it is not very realistic to start imagining bitcoin at below 70k which is already a good landmark compared to the price of bitcoin in June last year.
I agree with almost everything you said but the aspect of saying it is not very realistic to imagine Bitcoin fall below $70k which is a lie. As far as Bitcoin is a volatile asset we can't imagine the limit it will dip and it fall. Bitcoin has once reached an explicit ballpark of $69k ATH in 2020 and fall even to $15k is about %75 dip before it regaind. So price is too por to think of when it comes to Bitcoin dip because it may even dip below $70k if market permit it's. The unrealistic price we may not think of Bitcoin going back is like $40k below.
a time will come when even if one bitcoin is shared at the ratio of 1 : 1000, there will still arise a global scarcity due to its limited nature which will invariably raise the price unconditionally due to monopoly lifestyles of those who have held their own bitcoin for long without panic.
Of course at this point Bitcoin will start counting in sats, this mean 1 SATs will be valuable. People will prefare stacking Bitcoin SATs.
