with regard to the issue of power being everywhere: there
are certainly some phenomena that are ubiquitous and thus
unhelpful in explaining other things (gravity springs to mind).
The issue of interest with respect to the "micrpowers" lies
in Foucault's observation "where there is power ther is
resistance". Ubiquitous power *and* resistance is more than
relevant to MacKinnon's argument....and she would do well
to read a volume such as The Gender of Power, which contains
explicit attempts to confront "a Foucaultian analysis".
