In Finland this is solved by it not being possible to avoid state pension. You can collect your additional stash, but if you're getting a salary, you will be paying to the pension fund.
Yes, women live longer, but in general have a bit smaller pension due to their time off the workforce because of motherhood, and (still) slightly lower salary levels. I don't consider this unfairness towards men any significant issue.
