I do want to see localized nostr, but I don't know what is the right way to implement it. NFC check-in would be a way for local businesses to extend coupons, menus, or what-not to customers via nostr.
Speaking of which I don't think using peoples' IP is a legitimate way to determine location because 1. It's not voluntary, and 2. It's not always accurate like if they're on VPN. Maybe it could be communicated opt-in and natively via nostr
