Sorry, but I don't understand your point. How is this "degrading critical infrastructure" and "increasing the cost of market entry"? It's also not using someone else's resources - DNS hosting is a web service like any other. You pay for it either as a part of domain registration/renewal cost (when DNS hosting is included in the registrar's offer) or separately (e.g., Route53 or "Advanced DNS" offerings).

DNS is a Domain Name Service. Not a webservice.

What you're not understanding is the way DNS works is the closest DNS server to you (usually your ISP unless you've configured it differently) usually caches the results and then serves those results for subsequent requests.

So you are relying upon the server that is caching those results to serve your data. The intent of DNS TXT records was not to provide you with a content distribution network for free.
