There are BS/MS, BA/MA, BBA/MBA, and BSL/JD programs (asking others) that do not require a prior undergraduate degree but instead incorporate a same-field undergrad degree into the graduate out professional program, with typically less total coursework and tone in residence than separate programs would require because of right integration.

Yes, but there's no reason that a bachelor's degree needs to be an admission requirements for that to work; it may be a completion requirement, but that doesn't mean it needs to be an admission requirement.

The comment I was replying to was saying, in effect, "I want to be able to earn a graduate degree without having to earn an undergraduate degree".

Those programs sound great. They would allow a person to EARN both the graduate degree and the underlying undergrad.

That comment specifically complained about entrance requirements, so, no, I don't think that is a fair characterization.

I highly doubt that the motivation behind that comment is a desire to audit a masters program.
