Absolutely because the States OR Congress have no power whatsoever to prevent women from traveling from State A where abortion is illegal, to State B where it is legal.
State A is absolutely powerless to prevent a woman from leaving its borders to have an abortion. The Privileges and Immunities Clause guarantees 110% unrestricted travel from State to State in order to find the best combination of laws a person wants. This Clause eviscerates Congress' power to regulate travel for ANY purpose, including abortion.
A woman is 110% free to fly from Oklahoma to New York, and there is no Legislature, Court, or Law Enforcement that has the power to stop it.
If Roe v. Wade is overturned, Conservatives are going to have to realize that it will come at the expense of Federal power to regulate abortion, and the expense of State's being only allowed to regulate abortions that actually happen within their own borders.
