"Why shouldn't I expect anyone else who is in the air to do the same? If it's too difficult... ... they need training, if it is still too difficult they need to find another hobby"
That attitude reads as breathtakingly ignorant and arrogant. Maybe you need to find out about other types of flying. Paramotors, gliders, microlights and many vintage aircraft often don't have transponders and many don't have radios either. In order to stay safe you need to be aware of that when you're flying around in Class G.
