>it's too risky to skimp on restraints, you need multiple redundancy to minimize the chances of escape
If you need overkill to achieve basic results, that's on you.
If you use only what's needed and manage to fuck it up, that's on you.

Besides, you're ignoring one the hottest possibilities: taking a sub who really wants to be restrained and then giving them incredibly flimsy restraints. They can obviously break out of the restraints whenever they like, but the point is that they don't want to be freed.
