The worst is that I get some people like you to travel as passenger on my plane.
I would not object if you sit in a kennel in the baggage compartment.

@Dave C,My guess is that your not a pilot?I can understand your thinking/reasoning but there are times for the reasons stated by others when the 4096 code transponder(four digits ranging 0-7 inclusive 8x8x8x8x=4096 possible codes)must be turned off.
I'm a hobby pilot.But I earn my living running a poultry farm and driving HGVs (in the USA you call them "rigs" or "semis" I believe).The supermarket chain I drive for has satellite tracking on ALL it's fleet in which also relays trucks speed,acceleration,time to destination,drivers hours(tachograph hours) remaining....you name it similar to ACARS via SSR transponder,and it cannot be disabled by the driver(not without stopping and taking the fuse out).In an aircraft flight deck environment if an electrical system cannot be disabled at all and it was to cause a fire the burning would give off toxic fumes and damage other systems.
Unlike a truck you cannot just pull over in 15 seconds or so and jump out if it sets on fire,so the pilot MUST be able to disable it if necessary.
You could possibly have some other tracking device isolated away from the flight deck that is low current and voltage(possibly separate 12V battery powered) that transmits position via satellite similar to a cell phone as a tamper proof backup.However such a device would not constitute what is a transponder.

Because this sort of things has never happened before.
And because, like all other equipment, those things need electricity and could fail with a short circuit that could cause a fire that could burn and aircraft, if they were not protected by circuit breaker.
That is why.

That is 'cause the I.T.U. staff have not yet writen a rule to do so.
But, you could write a letter to I.T.U. clarifying your personal viewpoint about,
I am sure they will consider your message very important.

Hello Dave C...
I suppose your copyright for transponder is one without OFF or STBY position -
So, if there is an electrical short, let it burn the entire cockpit wiring -
And black smoke overcome the pilots -
The only "crap" is your uneducated suggestion -
