Beg to differ. A safer choice IMO is that of 67/33 global stock index fund and gold based 'digital coin'. Inflation for that did spike to 10%+ levels in the last quarter of 2022, but as of June 2023 is back down to near 0%, and where historically since 2009 consumer price inflation averaged -6.3% (your 67/33 stock/gold "digital coins") gained purchased power).
Let's call that Enhanced Digital Money (EDM), relatively easily created in any country where a global stock index fund and gold are accessible/available. Stored in a Wallet, such as a ii brokerage account (or whatever brokerage you may prefer). Exchangeable for actual cash in your regular spending account (or converting cash into EDM) in typically T+2 trading time.
The government pushing a central bank digital currency (CBDC) backed by the Pound - that tends to lose purchase power over time, and where such CBDC opens up all sorts of other potential government meddlings ... and for the average individual that is NOT the safest. Safest only if you are one of those in control of that CBDC.
A factor is that they're pushing a inferior product, where given the choice many might prefer a different unit of money, such as EDM, and where their regular spending account from/to which that can be sent/converted isn't controlled by the state/central bank, but instead is private and directly exchanged between individuals.
In the push for CBDC for that to be successful it will require the ending of actual paper/coin money, and will require increases in controls/lack of privacy, and some pretty hefty regulations, much international agreement and collaboration, and considerable controls to block data communications with any country/entity outside of that block. Where failure to achieve all of that could see the Pound collapse as a currency that no one else wants and the associated loss of central bank/government controls that would entail. Along with a period of exceptionally high inflation that such a collapsing Pound would drive.
But we are where we are, the Sunak, Hunt, Bailey first team and their apparent choice of a managed UK decline approach. In other news I read today that thousands of the 1% that pay a third of the tax take have already either self exiled or have preparations for such being established/in-place. Upon completion of their apparent managed decline policy so the remaining rest will be left having to pay 50% more in taxes just to fill that hole. Pretty much a certainty, given that the BJ/LT/KK opposing direction choice has been firmly vilified (largely due to incompetence in actual management/roll-out).
