Two problems with Patricia Aas's claims:
1. Hosting data on DNS is just using someone else's free server. If you have a domain you can also host your data for free on dozens of free static site providers that exist out there (GitHub, Firebase, Cloudflare, Netlify, surge.sh and many others)
2. How many people have their own domain names? NIP-05 allows you to use your own domain name, but also services to provide names for their users and groups of people to reuse names -- you could do this with subdomains too, but it feels weird, doesn't scale and probably means someone manually editing DNS records on a junky registrar interface.
