Flat-out wrong: there are many use cases which require multiple requests (you only mentioned CSS/JS but images are significant, too) and this would be exhibit A for an HTTP deficiency: you've internalized the idea that a visitor to the site must download and process EVERYTHING you could ever use to avoid making multiple requests, wasting bandwidth and device CPU/memory because you're trying to use asset packaging as an end-run around protocol shortcomings.

As for databases, this was a fascinating and completely irrelevant digression.
