This is the case for many life decisions. I don't see how this is a helpful addition to the conversation.
* Move to another state? There will be big life implications.
* Change careers? Ditto.
* Go to college?
* Go _back_ to school?
* Spend loads of free time hacking away instead of getting out of the house?
* Travel a bunch, perhaps at the cost of rapid career advancement?
* Take a huge pay cut to work on something you enjoy?
All of these (and more) will limit you in various ways, but gift you with different experiences. The same is for kids.
It sounds like you don't want kids. That's cool, I'm glad you know what you want. But no need to hype up this decision to have kids or not as scary or some kind of albatross. It's just another decision with pros and cons.
