One can go very very deep, as long as there's no expectation to get back up again alive. Hoping to get back up alive, the depth-limit sort of goes "from where I can safely egress". I much agree with the typical rec-limits of 18m/30m, since most rec-training does not prepare divers for anything deeper (some would say that 30m is stretching it -- I may be tempted to agree). Ask an AOW-graduate from most instructors what "SAC" or "gas plan" is....
One should never go deeper than one can safely egress from. People have sustained simulated depths of 701m (Comex in France), and deeper is probably possible. But egressing from those depths is not at all trivial
As for insurance: that's one of those things that I have, and that I plan to "waste" money on for as long as I dive. I say "waste", since I also plan on never having to use it...
