So if I understand correctly now, you _do_ proclaim to put asserts, not write code that somehow copes with the "possiblity" of NULL.

"Because no one is expecting it to work if a null is passed", so you can do whatever. If you write an assert for every pointer passed to every function, that will be a lot of asserts, for pretty much the same outcome in practice. Asserts are just marginally more ergonomic when they trigger, but are a nuisance in the code often. So my position is to use them judiciously, but not overdo it, be instead focused on the actual task.

When the lack of non-null assertions is an actual problem during development, you have much larger structural issues.

Yes. The work to assert each pointer passed into a function isn't "high"; it's purely mechanical, it could almost be refactored automatically. But most of all, the effort required to prove you don't need to is _way_ higher.

I thought so, too, at some point, and I put it to practice, actually did that for a long time. (I'm not _that_ much of a talker, I can back up what I'm saying with real experience having erred on the opposite side for a long time).

I thought so too, for many other things, and did so too in practice. Then I was doing thousands of little tasks in order to improve "security" and "correctness" and "proving everything", and never got to actually do anything useful, and my code became bloated to the point it didn't get to do much useful work.

Now I'm more considerate, trying to weigh everything in the larger context, is it REALLY required to get my job done?
