Very much not. The lft and rght values are an inherent part of the tree structure (it's a Modified Pre-Order Traversal Tree if you're interested). Without them, there is no tree structure.
The Acl system can be used to repair a damaged tree based on the parent_id fields, but without the full left and right stuff, it just won't be able to do aco or aro lookups, which is pretty fundamental. I would recommend using the Acl behavior, which implies the Tree behavior too, as a means of editing these values and having the MPTT stuff handled for you. For a clearer explanation see google on MPTT (or the forthcoming cake 1.2 manual... when I get round to it - sorry John!)
