What do you want the circuit to do?
If the transistors survive the load's current then the circuit allows a cheap little pushbutton or toggle switch to turn on the high current load.
you must have removed your schematic, or it's hosted somewhere my ad-blocker has removed, as I can't see anything
good solid state buttons:
capacitive discharge - check out quantum research corp ... qprox.com
IR beam break / reflection - ir emitter + ir detector arranged such that a finger near the 'button' will reflect ir into the detector - modulate the signal such that random IR doesn't interfere.
Bi-directional LEDS - two leds working as a light source and a light detector, if both indicate a change, you could interpret it as a "button push"
If you connect those two wires with anything low resistance, it will burn out the transistor. You need to add some resistance in series with the lower wire.
I agree this circuit is flawed in other ways as well.
The simple circuit is fine. It is two cascaded emitter-followers. Short the input to the supply and if the 2nd transistor can handle the load's current then the base current of the 1st transistor will be very low.
