Besides, the practicality of going elsewhere for abortion is a huge Q. For most people arguing for it, it's only a mental exercise. But we once tried to replace prescription glasses my wife left at home while on a trip in the UK. It's effectively impossible, don't tell me you can just walk to a clinic being a foreign national with no residence in the UK and ask NHS for abortion.
