Because you need a feedline to get the RF outside without half 
your
electrically-short antenna inside a building, with circulating 
current
losses to the many grounded structures all around on its way out.
50-ohm feedline is abundant and available.  Matching a short 
capacitive
antenna with a tapped coil at the other end is not difficult. 
you could
even use a mobile whip like a "Ham Stick" with a proper 
counterpoise.
Mount it somewhere on the fence where the fingers of curious kids
do not go.  It will work.
