Can anti-abortion States prevent travel for an abortion elsewhere?

It is a legitimate fear and doubtless some of these backward States will try to make it illegal. But according to this article:

"But can states decide that their residents can't travel out of state for an abortion? No—and it's not even 'especially difficult as a constitutional matter,' writes Kavanaugh in his concurring opinion. [...] A state cannot bar its resident from traveling to another state to obtain an abortion because people have a constitutional right to interstate travel, suggests Kavanaugh."

 

But then again, we know he is a confirmed liar and the Gilead Gestapo Corp won't hesitate to overrule existing law to suit its agenda.
