That's the whole point. The thought process "what would we need to combat a 1918 style pandemic if it happened today" does not in fact lead to stocking up on the things you're suggesting every country should have because they're supposedly required for any pandemic, since in reality those things weren't part of the plan for a 1918 style pandemic. If the political landscape was different it's entirely possible that (for example) mass PCR testing wouldn't be part of the plan for this pandemic. Most Western countries have the ability to use it for surveillance and estimation of disease spread during a pandemic, but trying to test everyone and use that to stop the spread is not a normal part of the plan for a disease like this.
