[Grammar] 'do what you want' or 'do what you want to do'?

[Heidi]

Dear friends,

I looked the word 'constraint' in my dictionary, and it says 'something that limits your freedom to do what you want'.

I was wondering if it were clearer or redundant to have changed it to 'something that limits your freedom to do what you want to do'?

Is 'he was not allowed to do what he wanted' or 'he was not allowed to do what he wanted to do' more natural to you?

Thank you!

Both versions seem natural to me.
