So if you were given the choice of having two currencies. One with inflation and one without inflation. You would pick the one with inflation?
If having = "to personally own with the hopes that the price goes up", then you pick a currency with limited supply.
If having = "to have it be the currency on which your entire economy runs", you should pick a currency which doesn't have a limited supply.
Dollars were in limited supply too, and they aren't anymore for a very good reason. Here's Ray Dalio trying to summarize some of the relevant economic principles in a video - https://www.youtube.com/watch?v=PHe0bXAIuk0
As you're pointing out, currencies don't have built-in inflation or deflation, that's why it didn't make sense to answer the exact question that the parent comment was asking.
