You have it backwards.

• Day 2 Purchase
• Day 1 “Theft”

Chronologically, the “theft” comes first. And you can easily purchase something you previously stole.

Theft is in scare quotes because piracy isn’t theft and I’m assuming OP isn’t going to actually steal someone’s Steam Deck, Switch, or Switch game cartridge… but maybe I’m wrong.

(Also you could “steal” it after purchasing it by buying on one platform and pirating it on another, but that’s a separate matter.)
