Lets see if I understand this:

The body is basically a box with a view finder. Not much else. The finder is actually not part of the body.

It needs a film back.

The lens comes with a shutter just like a LF lens.

So a working system would include a lens,body,finder and back? It seems that the prices on these have dropped a fair bit. Or am I missing something? I've been thinking off and on about a bronica 6x6 camera [forget the model] but the Hassleblads don't look much more expensive. The downside seems that the lenses are mostly expensive. OTOH I can live with just an 80mm.
