Essential is defined by what can arguably save lives and not create more load on the health system of the country.
For example: Pet food is currently deemed essential because you can't have pets dying on their owners and creating a health hazard.
Another example that makes sense: Selling heaters and spare parts.
I'm not convinced toys prevent domestic violence. You can always make toys with a bit of imagination though.
idk about the domestic violence angle, but bored people are more likely to go out and expose themselves/others to the virus. seems like anything that keeps people inside voluntarily should have at least a low spot on the priority list.
