> It feels like the sky-high valuations of technology companies and Bitcoin are "shock absorbers" of sorts, or early signals of inflation-yet-to-come. If we assume the market is efficiently pricing these assets (like AirBnB's IPO) then it could very well be that the actual value of a fiat dollar has dropped dramatically -- making sky-high valuations more reasonable
To me, the most reasonable interpretation of these valuations is a savings glut. People are being given extra income, but instead of going out and spending it on more impulse purchases (such as fine dining or an exotic vacation), they're shoveling that into savings accounts. And assets that reflect a long-term saving mindset--real estate, stocks--are going up in price, while more immediate consumptive assets (e.g., food) are staying stable.
> wouldn't be surprised to see the price of things like groceries, beer and travel double or triple what they were in 2019.
That would be an effective inflation rate of 100-200%. If you're assuming that would happen within a year, the number of countries right now with that high of an inflation rate is 3: Venezuela, Zimbabwe, and Iran. Even the developing world doesn't regularly see inflation quite that high, you'd expect more like 10-30% annual inflation for those countries.
