habits are 'remembered' in a different part of the brain than 'memories' so in many ways, a person with the form of amnesia you're talking about (retrograde amnesia, I think?) would still be the person he was before - many of our personality bits are as much habits as 'memories'. Liked and disliked foods, for example, physical quirks etc.
What would happen is that the person is quite likely to quicly become 'different' as he goes through new expereinces, mostly because our reaction to expereince is heavily based on memory - and he'd be rebuilding those reactions in a totally different enviroment.
And to answer your last para: he's not reduces to an infant, he's just not the same person he was. If he's able to congnate, and have informed consent, then there's no reason not to treat him like an adult.
