I don't disagree that you should know core concepts of what you're writing. I write a lot of Go without any heavy abstraction libraries (i.e ORMs) and have done with others like PHP in the past too.
With abstraction there has to be a balance though. Sure, I concede that knowing how it works is actually important, hence why I've spent a lot of time doing things without libraries in the past, especially as I was learning. It actually enrages me when people who've only ever used ORMs make super basic mistakes when writing and executing SQL themselves for the first time, i.e selecting a bunch of relationships in a loop one by one, instead of getting them all in one query. Stuff like that is a good example of how only ever working with abstracted versions of your tech stack results in mistakes down the line that have costs, since the abstracted version doesn't explain these concepts to you.
However, when it comes to actually trying to get things done efficiently, abstraction can help a bunch. Writing a bunch of stuff from scratch every time is not particularly productive either.

If you were to describe that in offline terms applications would be like books and abstractions would be like parts of the books. In order to make effective use of the book you still have to read, from scratch (whatever that means). When you become well versed in reading and writing it doesn't feel like a chore and you become far more efficient at it than simply guessing at the material from selected paraphrases. Programming is no different.
I'm not really sure what you're saying at all? It seems like we have agreed but I simply cannot comprehend your example.
The point I was making is that we could all spend our time going as deep as possible with as little abstraction as possible and end up writing stuff in assembly because "it's important to know how something works".
There is always a cost/benefit with abstraction when it comes to getting things done.
