I don't think the 7 sisters thing is implausible but i find unlikly due to the fact of Ren and Nora also being orphans and they turned out just fine

The fact that someone didn't want to lose him is a valid theory and most likely as if his Father died and his mother forbade him from following in his footsteps and that would explain his lack of training. But he aspires to be a hero like his family but doesn't think he's good enough not knowing any of them well enough.

He could have stolen the sword from the actic or whever his mother or guardian hid it and made off to Beacon. This could support my theory that a family member (most likely said guardian) will out him but it will be when they try to bring him home.

A hole in this theory is that Jaune is currently fighting in areana which seems to be broadcast across the world and this would out him to his guardian/sisters and that he wouldn't take that risk.

My counter to this is that he probaly didn't take that into account in heat of things or just forgot about it.
