I think that’s it, yes. (No offense intended.) Different languages have very
different ways of doing things. C++ has a very intense focus on performance,
and that’s led to its object model being very limited (I could say “crippled”)
compared to almost any other OO language. Part of this is the way that static
methods are really just namespaced functions, not true methods.

No, it’s a side effect of the language design. I could go into more detail, but
I’d just be repeating what Brent said, basically.
If you really want to dive into this rabbit hole, I suggest learning about
Smalltalk, which is in most respects the original OO language, and the direct
ancestor of Obj-C’s OO features. Metaclasses are a pretty deep concept and well
worth learning about. (I remember poring over the class hierarchy diagram in
the flyleaf of the Smalltalk-80 “Blue Book” as a college student…)
