So, the Fed and its 2% inflation target is a good thing huh? My first new car I bought (1971 Ford) cost me $2,000, now what will 2K buy me. So, give me BTC any day for a long term parking of funds. If, when, we get a world wide systemic economic collapse, then the "absurdity of BTC" won't be so absurd.
the discussion around inflation/deflation itself can last forever... but in a nutshell, a 2% inflation target is Fed's safety margin to avoid a deflation spiral.
Japan has shown us what a spiral looks like. The price falls, people hoard money, people hoard money and price falls more.... vicious cycle.
For the everyday economy, such as your car example, a mild inflation is not an issue.... yes 2k today won't buy what it used to buy 20 years ago, but you are not earning what you would 20 years ago either.. inflation encourages investment and risk taking.
You gotta think for yourself for a minute on this one
.... it's too easy for the bitcoin/gold/silver pushers to go poopoo on the idea that the Fed is printing the dollar into worthlessness, but in the meantime the central bank was created for the exact reason that stuff like btc/gold/silver can't possibly handle the modern commerce.... imagine if we were on gold standard in 2008... we could actually not find bread on the supermarket shelf.
