Now, if you start establishing some rules about the type of code I'm allowed to write, then your statement becomes truer. But by no means do people actually follow that in the real world all the time.
If you wrote a program that is 1,000,000 lines of code you could also write a blog post about your thoughts on "writing 1,000,000 lines of code".
You could also write a program that is 200 lines long and write a blog post about "writing 200 lines of code".
One is not better than the others, you are just informing your audience of the topic under discussion.
I think most conversations around LOC assume that it's not an idiot writing it, and I think in general, this is a good assumption to use when it comes to code discussions.
It’s not a great metric. But it does communicate something about the scale and complexity of a codebase.
