There are many incentives for women. Think about tax cuts for starting a company, etc. etc. Do you want to remove those incentives?
> If this passed, could I become 65 and start withdrawing my 401k penalty-free?
Well, women (at least in Italy or Europe I guess) can retire earlier than men. So, can a 60-year old become a woman and retire, while as a man he would have to work until he's 65?
You haven't thought this through.
I'm from the US and haven't heard of this before. Is there a widespread rationale for this? As a whole, women live longer, so equating "retired years" doesn't seem plausible.
In the US, you get (easy) access to 401k and IRA at 59.5 years old, and social security can't be claimed until 62. Gender doesn't matter.

As for the UK: the Womens retirement age used to be 60, but it has been steadily rising for some time, until at one point it was brought to parity for eligibility for state pensions. (a move that was marred with protest by those wishing for "equality"? somehow)
