Why?

Perl, Javascript, PHP, Flash, Java, shell scripts, .Net, VisualBasic, and 
hundreds of other languages have been successful for decades, and they all 
require either an interpreter or a runtime environment, or both, to work.

Why should Python be treated any differently?

If you want to include a Python runtime environment with your code, either 
include a version of Python, or use py2exe to wrap the Python runtime 
environment and your code into a single executable.

Unless you are writing device drivers for hardware, or operating system 
kernels, or a few other applications, compiling to machine code is of limited 
value. And even where compiling to machine code is useful, it is often better 
to use a Just In Time compiler that compiles the code when it is run, so it 
can take advantage of runtime information about the data. A good JIT compiler 
can often beat a static compiler for speed.
