The last BTC mined will be 2140, but the decay is exponential. The reward will halve in about 3 years, and it is likely to halve again 4 years after that, and so on.
The gold standard was the least of the Bretton Woods Era problems.
I also wouldn't call this new fiat regime with rising property prices and stagnant wages as a "net win" over Bretton-Woods, the gold standard was probably the only thing keeping the federal spending under control, and real wage growth up.
Price appreciation has to stop at some point. I doubt the price will rise to $10M after the 2028 halving so miners will be under substantial pressure by that time.
