As far as I know monastic life is not really work-free or worry-free. It's still a society with a lot of baggage. You are even expected to work for free and don't question the authority of the "upper-class".
The only chance to be "free" would be to live in a very remote area, alone. That's a tough life but at least you don't have any answer to anyone.

That's the route Daniel Shellabarger [aka Daniel Suelo] took[1]. He quit his job and went to live life as a hermit/hobo in the Am-Southwest. It's not an easy life --most people would not take that deal, but maybe for him it is. It's very ad-hoc and with very little regimen.
I doubt that Nature says that only males are allowed to enter.
Unless you are a hermit and live in solitude (which is not the case on Athos) you still have to answer to the community members and obey the community rules which very are often made to favour specific members of the community.
