i calculated the average increase of roughly 7%-8% for the last 20 years, according to the site you mentioned (+490% over 20 years). And, you look at inflation of almost anything from housing to gas, most of it averaged 4-4.5%. We hardly need a basket of goods to average across anymore since most of people's earning now go to housing, at least for the latest generation. Case shiller shows housing was already going up at 4% per year on average for the last 20 years, and that was before the pandemic. So, yeah, the dollar and all the other fiats, for the last 20 years have been crashing at least 4% per year. and the CPI, as it was calculating using the older methods (before congress told them to start under-reporting inflation) can confirm this. You can find out all about this on http://www.shadowstats.com/alternate_data/inflation-charts if you read all the foot notes you can find out inflation measurements have changed in order to under report it.
So, we had at least 4% pre pandemic and now closer to 10-11% (real CPI as reported on shadowstats, is always about 2% higher than the fake BLS numbers) per year though it looks like it will diminish.

That's not a crash, that's more-or-less by design. Currency, i.e. money, is engineered to be inflationary and economists consider the optimum inflation rate to be 2%-4% per year. For the past 20 years we've been on the high side of that target, but we're on target. Inflationary currency encourages investment and spending. Saving currency in the bank is not producing value (there's even a parable about this).
there's already a vast oversupply of investment money chasing far too few opportunities: take a look at the s&p500, it's only returning 1.3% dividends. that tells you PE ratios are through the roof and that there's too much capital chasing too few opportunities. so, there's no need to "encourage investment and spending".
Society would have a lot to gain from a government that didn't default on it's obligation of "money as a store of value". there's a large need for store of value, especially with the aging population.
Money is most emphatically not a store of value and hasn't been in over 100 years nor do you want it to be. Hoarded money has little value to an economy. What you want money to do is be used to build or expand manufacturing, build or expand shipping infrastructure, communications infrastructure, expand agriculture, and so forth and so on. "Investment" is a much broader term than just buying equities. Do something with your money! As I said, there's even a parable about this.
