We all know inflation is a thing. It is a common attribute for all viable currencies and is considered to be essential by economists as it encourages people to keep moving their money rather than stuff it under their mattress like with crypto. My high yield savings has surpassed the inflation rate every year I have had it while having the least risk possible.
Your debasement stuff is commonly used as a fear mongering tactic by people with an incentive to get you to buy their specific investment. For example you posted a Big Mac picture that Bitcoin people like to post to show shrinkflation when the actual claim is completely unfounded.
Social media users claimed the well-known burger fell victim to shrinkflation.

You still seem to forget that part of the risk assessment is what will occur to your money/assets in a downturn and how quickly those assets can be liquefied if needed. Money Market / High Yield accounts are some of the safest savings platforms that can be used for emergency funds while remaining liquid and keeping up with inflation. They also wont tank with a *insert your investment here* market crash.
Trust me, I am 100% against too much savings. You need to make your money work for you. The problem we are talking about is for financial security which necessitates safer investment platforms. Even gold can be volatile.
