What if products had a Nostr *NPRODUCT* instead of the usual GTIN (UPC/EAN/JAN/ISBN/etc) code?

- Manufacturers would own the digital identity of their products, for free, without be locked in the proprietary GTIN (UPC/EAN/JAN/ISBN/etc) market;

- Nostr e-commerce/reviews apps would have a better integration for products, with a news live feed from the manufacturers;

- Manufacturers could offer a specialized customer support via DM using the product profile;

- Manufacturers could promote resellers, and possibily onboard them on Nostr;
