This is true, but the end of your post implies that recessions have become rarer and less pronounced in a fiat system. They haven't. In other words, sure, central banks "flooded the markets with capital and blunted the impact of the crisis and avoided panic", but what system was in place that allowed the manic colossal 1995-2008 housing bubble to take place? Did it not have anything to do with central banking policies, say, I dunno, incredibly low interest rates for a decade?

The interesting part about your post is that it is in response to OP asking if people would be willing to buy BTC at any price (to which you responded no). But you gave the perfect example of mass psychology encouraging people to hoard an asset they believe to be safe: in this case, in 2008, it was the USD. Despite 'printing' (yes, I get it, it's not literally printing) massive amounts of USD, the world ate it up because the USD it the world's reserve currency and they (correctly) assumed that if the US is in trouble, every one else's currencies were in waaaaay worse shape. Thus the insatiable demand for something that was becoming 5x less scarce.

Now, if Bitcoin ever reaches that level of belief in its capacity as a store of value (for example, based on the fact that for the first time ever you have a currency/scrip/asset/commodity whose entire supply is predetermined, fixed and immutable politically, could you not conceive that it might to have buyers flock to it? (not asking if it's probable, only if it's possible; I'd agree that at this stage this isn't the case)
