If you are going to keep working and you have [more than] enough to meet your regular needs, why on earth would you consider yourself better off having access to more money now--money you admit you don't need and don't want to spend?
Now, if you are young and going to part time but that won't cover all your expenses and you have absolutely no money in accounts you can access before traditional retirement age, you do have a bit more of a legitimate concern, but I'd first look at a conversion ladder and the other options to see if that would be sufficient, or sufficient by the time you actually quite working entirely.
