This is a matter of personal preference of course. But the way you phrased it, "a whole life in full freedom" tells me you think it's either all or nothing. If you can't enjoy the full freedom in the last years of your life, does it take away from the previous years?

For better or worse people with kids know both lives, people without kids only know one. It's like saying "you'll never know how it is to eat an entire cake". Maybe you ate much of it, that counts for something. Now you're on to the next cake. You might bite more than you can chew but this goes for everything.

The value of this freedom is the highest when you're young, experimenting, putting your life on some track. Being "free" at 65 doesn't have anywhere near the same value as it does at 20. Once you do it (almost) all, everything else becomes more of the same doesn't it? That cake I was mentioning? The first bite tasted a whole lot better than the last.

There's no right or wrong, everyone knows their preference and personal circumstances. But your explanation felt like a knee-jerk reaction.
