You don't choose to become a "black code" by doing a PCR test; you choose to become a "black code" by becoming a delivery person for foods and goods, because when people are in lockdown at least you need to allow them to shop online. At least that's what I've heard. It does not mean the government will necessarily allow online shopped goods to be delivered, and it does not mean you don't need to do PCR tests.

Rinse and repeat.
