Try buying microsoft.com or wsj.com and if you can't, try storing your NIP-05 on their server! Does it make sense yet? As for me, I might be Dave Smith who registered mikehardcastle.com I might even setup my WHOIS as Mike Hardcastle, but I can't fake my purchase card or matching invoice address. The power of anonymity that NOSTR offers works equally well in reverse for people that want to be verified, which is why that fake Wall Street Journalist didn't hang about for long when we asked her to confirm her NIP-05. I was also approached by a fake ID from a BTC mining company, they said they couldn't upload their profile to the mining companies website, so I replied to her email and changed the domain to be the company she claimed to work for. It bounced back. I told her and I never heard from her again.
