This is analysis show real lack of imagination. Continuous glucose monitoring is extremely useful, even for pre-diabetics, let alone type 1 or type 2 diabetics. It does provide actionable information. Action isn't just inject some insulin (even though type 2 diabetics eventually go on insulin). Action can be don't eat. Or action can be go for a run/cycle etc. Or action can be adjust your medicine dose. Or drink a lot of water, or any other of the things available to immediately lower or increase your blood sugar. High glucose doesn't have many symptoms unless it is ridiculously high. If you have blurred vision, hot flashes etc, then it's really really high. But there are things you can do before it gets that high. And knowing you are trending in that direction is useful. Going for a long walk can help. Going for an hour or two bike ride can lower your sugar below normal. On the other extreme, if you just changed your medicine regimen (higher dose or doctor put you on new kind of medicine that works better for you), you are at risk of lowering your glucose too much. Esp. dangerous for medicine taken before going to bed. Recognizing low glucose is much easier (shaking, dizziness) but not when you are sleeping. Being alerted if you are trending below normal and keeping some candy next to you is always wise. Continuous monitoring helps in all these scenarios.
