what are the other options that provide the same level of safety as SGOV and no dollar devaluation?

So a lot of talk about long term bond yield going up which means the trust in long term bonds are dropping. At the same time the dollar is depreciating.

Assuming this trend continues its only a matter of time before interests are not paid and even T-bills are going to start having issues. where do you invest to save the value of your money and at the same time get 2-4% in returns? Lets assume this is not for the full portfolio value and Its only for your emergency funds. Basically trying to protect against short term storm.

Physical commodities like gold and silver are not an option because of storage, security issues and things can flip pretty quickly in the PM market.
