First, your math is wrong. It would take you 20 years to lose 40k on 200k at this inflation rate, but if you had the $200k 20 years ago, you already would have bought the house and not experienced the inflation loss. Which is my whole point. Who holds $200k in cash for 20 years? Nobody, because if you do that you're not very smart.
My math is correct. 20% in 10 years from 200k= 40k, not in 20 years! I was describing 20 years period. So if you started with 0 ended with 200k after 20 years you hold 100k on average - 40% in inflation during 20 year period = 40k. Situation when you started saving when you were 25 and buying house when you are 45. thats not an uncommon situation.
Second, -20% in 10 years is appropriate for an asset that is ]designed to slowly depreciate over time. Compare that to bitcoin which loses 20% in less than a week on a regular basis and there's no comparison.
Dolar is losing in value ... only. Bitcoin is mainly gaining. If you only don't shit your pents seing -5% 5min candle, relax, zoom out you will see that bitcoin had only 1 red year!:
From 2013 to 2014: $94 -> $600 (538%)
From 2014 to 2015: $600 -> $292 (48%)
From 2015 to 2016: $292 -> $624 (113%)
From 2016 to 2017: $624 -> $2,700 (332%)
From 2017 to 2018: $2,700 -> $8,100 (200%)
From 2018 to 2019: $8,100 -> $10,100 (24%)
From 2019 to 2020: $10,100 -> $10,900 (7.9%)
From 2020 to 2021: $10,900 -> $40,000 (266%)
Third, the handcuffs on macro economic prosperity created by the gold standard is much greater than the current system, which is why the world changed. I'll take the current system over the former 100 out of 100 times.
Elites strive for the greatest possible power over a crowd of sheeps. Thats why world changed.
