My take is that the USD will collapse only under one of two circumstances: 1. The US empire decides to do a rug pull -> suddenly and for no apparent reason, "end the fed" proposals start getting traction. 2. The last nuclear weapon has been detonated, in which case you probably don't care that much about currency markets.
The people in picrelated are talking nonsense, but they're talking their book. However, I would caution the "USD will last until the end of time" people that #1 is not impossible.
This is the down-stream result of MK-ULTRA, converting people into foot-soldiers for the system without their own awareness or agency. Some people are easier to convert because of <below>.
I guarantee you the guy's not a plumber, he's probably working at a university that uses YOUR tax money, and that univ should get an immediate funding cut.
Why funding cuts? Because for every one guy who desecrates a historic landmark, you have 100 coworkers cheering them on.
When you cut the funding, you send a clear message: The taxpayer will not fund institutions where criminal mischief is normalized.
When that message comes down, you'll start to see layoffs, and the whole support network of these people will have to get a real job.
I don't really buy it. All throughout the 20th century, the US was floating loans to the USSR and then using them as a prop to coordinate in colonizing South-East Asia and South America.
