Surely that sort of public grandstanding will ultimately necessitate PM to up their insurance levels on all items and means that everyone will pay more for coverage that they generally don't need?
If I want to claim on my car insurance for a risk that I haven't covered, do I lament on national airwaves to embarrass my insurer into paying me? If I want full comprehensive with no excess, I should state that at the outset and pay more accordingly. Likewise if I have valuable goods in transit, I should cover myself before the worst case scenario happens.
