But if that's not the threat you are trying to protect against, there are locks that are sufficiently secure that picking or other "low-impact" defeat attempts are considered pretty much pointless. Abloy protec2 comes to mind.
The Canadian Mint in Ottawa has a rather impressive large gold bar on display in the gift shop for people to lift and take photos with. It's not in a case or anything.
It's chained down with a Protec padlock - and there's a cop a few feet away to deal with you trying something un-subtle.
To me that sounds more like a good endorsement for having a guy legally authorized to use force against you standing guard. Any old padlock is probably safe when a uniformed agent of the state with weapons of varying lethality is standing next to it.
You don't even have to go that far. Firefighters have core pulling kits that take care of 90% of all locks in 2 minutes tops. And for most other locks, the thing holding the lock tends to be less of an issue than the lock.
I had an Abloy Protec2 malfunction while locked (PSA don't use them for key-only sashlocks) and the locksmith drilled it out in ~10 seconds. That is the last time I spend that kind of money on a lock!
Doesn't even need to go as far as using power tools.
Every lock I've been unable to pick (usually due to the fact that it's a pile of rust) has been susceptible to bolt-cutters. Big lock? Bigger cutters. Still cheaper than an angle-grinder.
