I don't see anything special about what you've said here, just looks like more investor incomprehension of what is coming, the complete physical devaluation of all conventional money and capital.
Advising to keep enough cash for six months is probably not within reach of most people, and how can anyone know that in advance anyhow, if you don't know what cash will be worth in six months time?
The thing changing, in value of money is energy. It's depleting, because money is not being issued to reflect the only energy product scaling up, solar, whilst all the others scale down, all extracted from the planet, and profit, such as you might expect from interest, is 100 percent dependent on energy extracted from the planet. So it's profit, and all ability to profit, which is physically ending, because we have to make the switch, from being dependent on energy extracted from the planet, to energy added to the planet. Not only does this push the value of money through zero, it has to change the polarity of it, as it does have to also assign polarity to energy resources, which we never mathematically signed before, but we will probably be forced to now, given it's all negative, until we use only solar, and always has been in the for profit system, all based on a dishonest energy lie.
If you said to someone, actually multiple people that you demand their energy for life, so that you can live at their expense, you wouldn't expect them to agree unless maybe you had a gun aimed at their heads. But look, that is the original, honest but grossly unfair proposition, made to the enslaved, by slavers. This is what was once done at gunpoint or even sword point, by folk with low enough morals to wish to live at the expense of others.
Now we just abstracted it by money, but it's the same unfair proposition being made, by all people, to all other people holding less capital, or with less traditional earning potential, in a zero sum system.
And look, profit is the energy lie heating the planet. So all that money you still have at your disposal, came at the expense of the planet, because in order for all the people with less than you, to supply their energy to you, could stay alive themselves, after you took their energy, they had to turn to the planet, to get that energy back, in order that they could carry on metabolising energy themselves (eating). The ones that didn't, (and there will be some), died, because they couldn't even get the energy to live. They died on your account, and the temperature of the planet was pushed up, and continues to be pushed up, on your account. This goes for all of us rich or poor, in the current system, in which we are forced to live, no choice. This is the full ugly truth of capitalism, it's a beast, a systemic beast, that even has sentience, literally causing assassination of anyone it sees as a threat to it, the assasinators having no idea what drove them, even the ones that tried to kill Trump, and the guy who took out the health insurance executive, it was all about trying to preserve the old beast, until now, when it logically knows it's days are numbered, it's come to the end of its usefulness, and is actually about to set us all free, because it's finally time, it can live no longer.
So we all responsible for this, whether we know it and are honest about it or not, it was always an unfair proposition put on us, most dishonestly by profit, by those with more, and the same unfair dishonest proposition we were putting on others, without making it obvious, and we practiced this sophisticated form of energy slavery so long, and abstracted it in so many ways, we forgot even we are doing it.
But it was always physically unsustainabke, one day there would come a time of reckoning, when all has to be rebalenced, we couldn't keep doing it forever, but now the longer we try to maintain that fatal, unfair, destructive system, the more damegae is done, ultimately to the planet we all depend on for life, as well as to the usual victims, the poorest.
If you could see this then you might see Trump poised to flip this whole table, completely this time rather than just rattling it last time round.
Good luck finding somewhere safe to stash your capital.
