I do not agree that "nature or evolution is parsimonious" is one of the
assumptions of phylogeny reconstruction. Rather, we prefer the most
parsimonious tree because it requires the least amount of homoplasy. It is
the simplest explanation consistent with the observed data. Occam's Razor is
a statement about our explanations of reality, not about reality itself.

Not so. The three-word statement
"Nature is parsimonious"
should cover it. In the case of phylogeny reconstruction, the statment
becomes "Evolution is/was parsimonious".
"Nature is parsimonious" is the elemental, overriding assumption
(hypothesis) not only behind phylogeny reconstruction but behind all of
science. William of Occam stated it more eloquently hundreds of years
ago, and since then all scientists have shaved with Occam's Razor (pardon
the mixed metaphor, but it was too obvious to pass up). Much of science,
then, is the discovery (quantitative and qualitative) of how far/often
nature has strayed from pure parsimony.
