To add to this, just because medics have the training and authority to use advanced airways doesn't mean they're going to automatically go to those. (Though, sadly, there are some that do I'm sure).
Myself, I always consider basic measures first. Sometimes BLS stuff is all you need for a particular emergency, and as fun as intubating is when it's necessary, I'd much prefer to be able to just pop an OPA in a patient that only needs that much to keep their airway open., or an NPA is the situation fits. However, some patients require more than this, and that is one example where a medic does in fact make decisions as I have to decide with a particular patient whether an OPA or NPA is efficient enough or not. If in my opinion it is not, I choose to go with a more advanced airway. And in extreme cases where a patient is conscious enough not to tolerate an airway but they currently need or imminently will need advanced airway securing, I have to make the choice whether I chemically put them down to enable securing of said advanced airway. Just examples of decision making that goes on, all with the point that any smart medic will look at BLS first but have to make the decision as to whether that is enough or not. Has nothing to do with "being above" using BLS airways, it's whether or not that is enough for the patient or if we need to use more advanced airways we're trained and allowed to utilize.
I'm all for being able to use an OPA or NPA and nothing else. Less stress and potential trauma to the patient, less stress on me, easier for everyone. But I won't skimp and cheat and just use that for the sake of making my job easier at the expense of my patient's well being just like I won't automatically jump to ALS care simply because I can and it's more "fun".
