Who in their right mind doesn't see that 100 today is not 100 in 50 years. The 100 year Austrian bond was the height of lunacy as if Austria will be a Sovern nation in 100 years anyway? People who lend, banks ect are playing a different game with different ideas. Buffett buys treasuries to earn a bit while waiting for something real to come by like a railroad. He doesn't do it to make 1-5%
Lending money long term is tough to understand unless the rates far exceed the level of inflation.
In the 70's a big mac was less than 50 cents, today its 10x that or more. Our paper/ digit money looses value every day and has for a long time.
Gold was 154 in 1974 today its 2400. Gold is money, paper or digits is just for transactions. Does it matter what the transaction number is? 10-100-1000 its just a digit. Will my house cost 18 million Canadian in 50 years, maybe maybe not who cares as long as its roughly the same value as today. I bet it will, gas will be 12 bucks a L, gold 25k OZ. all just a number.
What we should care about is life expectancy, number of people starving, happiness, wars, have the leaf's won the cup ect
