The problem is people have a hard time of wrapping their head around the idea that an encryption backdoor, once created, is at extreme risk of being leaked to others and can not be contained.
This is something that I find is hard to explain to nontechnical people because it isn't intuitive of our understanding of the real world.
E.g. "If a bank can keep my money from being stolen, then surely you can keep this backdoor from being stolen, so stop complaining and just do it already!" -- As Trump would probably say when ordering it done, echoing the sentiments of many.
Point to TSA locks and the New York City master keys. Both systems are similar enough to encryption backdoors, and both systems have already been compromised.
