That's certainly not ideal, but still completely different. Many countries have understandably banned/slowed exporting these supplies. Some of those restrictions certainly went too far: Canada, for example, depends on US suppliers for some materials, and cutting them off completely is going to hurt them rather badly while, due to size differences, not being all that significant for the US. The same is true for some European countries. Sometimes country A depends on B for X, and B depends on A for Y. The first or second most important region for ventilator manufacturing, for example, happens to be... northern Italy! What the Federal Government in the US is doing is something different altogether. They're confiscating material within individual states. It's not even clear why they have jurisdiction. They seem to sometimes argue from a default assumption of shipments being destined for the black market, and otherwise simply rely on raw power, FBI badges, and ill-defined emergency powers.
