The normal market logic that high prices encourage extra production doesn't apply during an emergency, when the demand is panic-induced and momentary, and supply changes won't take effect until after the emergency is over.
The actual solution that makes sure everyone gets what they need and theres no hoarding is rationing: limit the number that one person can buy. And that's exactly what most grocery stores are doing.
I'm not convinced the US government, let alone any western government, has the plan, manpower or infrastructure in place to actually take over distribution of essentials in fair quantities.
There is no supply problem for consumer products. The shortages you see at grocery stores are exclusively because of panic-buying and hoarding, the shelves are stocked right back up to full overnight.
buying 1 pack of TP? $2. 2 packs? $5. 3 packs? $12. etc.
The people that truly need 1 or 2 can afford those. The people that want to buy 10 or 20 at a time will pay a huge premium, enough such that it won't really even be easy for them to turn a profit trying to resell to the people who got there 10 minutes after them.
