How exactly do you want to "enforce" an "optional" runtime type check for an interface, that is different from opting in by calling `isinstance`?
For that matter, `TypeError` exists and is raised non-optionally by all sorts of things.

For your specific set of dependencies, perhaps. Lots of people are using Python just fine. A large majority of what I'm interested in using would install fully (including transitive dependencies) from pre-built wheels on my system; and of those wheels, a large majority contain only Python code that doesn't actually require a build step. (Numpy is the odd one out here.)
In fact, of the top 10 largest packages in my system's `dist-packages` (all stuff that came provided with my Linux distro; I respect PEP 668 and don't let Python native packaging tools touch that environment), at least 9 have wheels on PyPI, and 4 of them have `none-any` wheels. (And of course, tons of the smaller ones are pure Python - there's simply no room for a compiled binary there.)

Python is too flexible. It produces sloppy code.
And in no world are Python builds and dependencies solved. It's a major headache.
