The ECB is now arguing that a CBDC is needed in case of power and network outages.
How do they say it would help?
1. The infrastructure will have multiple servers
2. The CBDC will have a dedicated app
3. The CBDC might work offline
This argument is far from compelling.
At the risk of shocking the ECB, let me be clear: private businesses already use dedicated apps, multiple servers, and even *gasp* back up servers.
In fact, offline payments might be tricky, but they are not impossible. Recognizing the value of connecting people in times of outages or disastors, the market has introduced solutions.

Yet, even then, it's simply absurd for the ECB to suggest that the central bank must intervene to introduce alternatives. As George Selgin pointed out in 2018, central banks are just as vulnerable to outages, equipment failures, and hacking as others.

History has shown that they too fall victim to these issues.
Furthermore, as George noted, there are plenty of alternatives available.
You can get multiple bank accounts, fintech apps, prepaid cards, cryptocurrencies, and more. And each one of these options has its own suite of subcategories.
So the idea that central bank is needed to swoop in and introduce a long-missing alternative is too little too late.
Arguements like the ECB's are why "a solution in search of a problem" has become the unofficial tag line for CBDCs.
