Have you ever been a LPR yourself? When you file I-90 for expired/lost Green Card, you can request a temporary stamp I-551 in your passport. This will be a valid proof of your status for any transaction within the USA as well as for entry into the US from abroad. Canadians also treat this stamp as the Green Card substitute. Of course, it takes some time (couple of hours) to get this stamp. Speaking from my personal experience, it is hardly an inconvenience.
Been LPR for about 6 years and never felt this way. Heck, I haven't felt this way on an immigrant visa. Even though it is a "debate" forum, I would still advise not to generalise one statement by a particular CBP officer onto the entire US government.
