> someone somewhere will decide these LEO satellites are used for the military against their own sovereign countries and will have to start destroying them
Military potential is true for all materiel. Including DoD satellites.
> We will end up with a graveyard in space where fragments will make it difficult to continue any space activities
No, we won’t. Specific orbits will get trashed. And even then, only for a few years—LEO deörbits in months to years, the latter only for small things in high LEO.
If you're determined enough you can cause damage that does not decay or go higher than LEO. This risk already exists for accidents. If your goal is to cause it, it wouldn't be too difficult
