They can’t stop people from going anywhere however they can take away tax breaks for or impose other hardships on companies that do pay for it.
Speaking of taxes, if a company were to pay for a trip from Texas to California for an abortion via airlines, possibly assist in payment for the said abortion, could not the IRS see such payments as a taxable “gift” to the recepient? Or possibly as income since your employer would be giving you money? Could that not raise the tax bracket? And we know California doctors will milk that for all it is worth, won’t be cheap!!!
And if a murder charge was pushed by the state, could not conspiracy charges also be used against the company, its officers and the woman/couple?
