For most remote jobs I've had there was still an expectation of some travel, usually 1-2 on or off-site visits per year. Further, many Big Name companies will ask that you travel out as a part of the interview process in the first place, remote or not. So long as there is no undue burden out-of-the-gate, i.e. you pay and or we reimburse, it's not particularly untoward.

Still, that wouldn't solve for the "My laptop doesn't have a camera" problem for the early phases of the interview. You would need to save face / voice samples to cross-reference at various stages of the pipeline to watch for the changeling.
