You have misunderstood Geoff, your retort is irrelevant to his point.
The name space collision Geoff is talking about is between your user
code and the CRT.

Do you know how difficult it would be for me to change the CRT I use
at home and at work such that it did have a __foo()? Don't think too
long, as I'd already have done it.

If you only care about your code running on one platform and only
using one toolchain - at that, only one version of the platform and
the toolchain - then you have the right to construct your own play
area where you break the rules. However, do not expect others to join
you there, and certainly do not expect others to want you to join
their play area.
