The best way I've found to orange pill those in the West who have never witnessed currency collapse is:

Have them scroll through https://bitbo.io/ and check the BTC performance relative to African, Asian and Latin American countries' currenices. This clears up any confusion instantly. Having the USD or Swiss Franc as your unit of account blinds you to the harshness of financial repression around the world.

My home currency has collapsed 50% against the US dollar within my lifetime. It hasn't been quick, just a slow bleed out. All fiat economies are steadily melting icecubes.
