YELLOWFLOWERS, my DH is a GP, so I felt I should reply and say YAB at least slightly UR!
It's true GP's function as "gatekeepers", firstly, to treat minor ailments, To refer to the appropriate specialist as needed. To spot rare, but dangerous symptoms (which have a habit of masquerading as minor self-limiting illness), and these can be very difficult to spot (because RARE THINGS ARE RARE).
Secondly, they are indeed there to stop you getting prescription drugs you may think you need, but which could actually cause more harm than good.
You may have a computer and half a brain (I think you mean a brain and a half ), but believe me, many people have a computer and no brain at all , and arrive in the surgery with all sorts of total bollocks printed out on 30 sheets of A4 - and they really do need someone to come between them and the medication they they they need for the illness that they think they have!
And that's just the genuine people, who in good faith believe they have some nasty illness - there are a lot of "users" out there who go to great lenghts to get drugs they can take or sell (much more common than you'd want to believe).
GP's don't get it right all the time (nobody does), and it's not a perfect service, sometimes things go wrong, but we are damn lucky to live here in the uk and have a GP service available to us, and indeed and NHS - I have relatives in both the USA (awful unless you are rich) and Australia (more like our system but you pay to see the GP)and they more you know about other systems, the more you appreciate ours!
I know this is the AYBU thread, and it's a great place to let off steam, but you know, they are not all bad!
