The track link price range is currently $0.50 to $0.90, so you're quite right
about it being unfeasible for now, but I was surprised to find that the
break-even point, below which the track link price would make a tracked monorail
track as cheap as the old monorail (assuming structure parts such as Technic
beams are already in one's collection), is above $0.20 for some monorail track
pieces (due to their rarity and popularity):
Taking the Bricklink price guide average prices, and assuming that it takes 44
track links to make a 33L straight equivalent to a 32L old monorail straight,
the track monorail is cheaper if the links are under $0.266 each.
For short straights it's $0.239 and for a short curve it's $0.304. For the more
common 90 degree curves it drops to $0.041 (I wish the tracks were that cheap
but it will never happen as they weigh 1.38g), and for ramps it's $0.075. It's
more difficult to calculate for points.
I'd like to think the scheme could become more feasible if the track link price
drops when the bulldozer is released. I hope it will! My hope is fed by the
recent drop from $1.00 to $0.90.
The additional possibilities for roller-coasters also increase the appeal...
