At my age, is it stupid to stay at home a few more years to save money?

If you can survive living at home, then i'd definitely try and save up so you can move out eventually in a comfortable way.

As long as that situation works for you and your parents emotionally, stay as long as needed.

Sounds a good plan, as long as your parents agree

Definitely not

As long as your parents are ok with it.

That’s a smart idea now make the decision do it and don’t allow your brain to over think it

Not stupid at all. This isn't the 60's, it's not easy to buy your own place these days or even to rent unless you like cockroaches.

the more you can save up front, the better.

No not stupid

You are looking ahead and making a judgement based on the best options available to you. That's far from stupid! :)
