I would instead ask, why not? As long as his memory requirements are
modest and fit within the 32-bit address space, what does using a 64-bit
kernel buy him other than more memory usage and if not still at least
until recently, non-compatibility with non-FOSS software that isn't
supporting 64-bit yet. Granted the latter is shrinking, perhaps to zero
by now, but still... the question remains, what's wrong with 32-bit if
memory requirements fit within the 32-bit address space?
I run a 32-bit kernel on everything that doesn't need the bigger address
space. Even on my main workstation, I run a PAE kernel to get access to
a bigger address, even if clumsily while still maintaining the 32-bit
userspace?
Why do I continue to use 32-bit kernels? Mainly because I don't
willingly inflict the weeks of niggling pain of trying to get a freshly
installed working environment back to what my pre-fresh-install
environment was. Instead, I always upgrade from one release to the
next. I have always done so for nearly 2 decades (barring of course
moving from one distro to another). When I switch from Ubuntu to Fedora
I suppose I will do a 64-bit install, or when Ubuntu fully and properly
supports cross-grades, I might consider it. But until then, 32-bit is
satisfying all of my needs and not causing me pain.
Ultimately, 32-bit is tried and true with a very long history of testing
and support. 64-bit doesn't have that history.

But yes, agree on that. Should be using a kernel built to take the
greatest advantage of the instruction set available on his processor.
