No, screw this whole ideology that we have to overbuild transportation infrastructure today under the (typically misguided) assumption that one day, maybe, in the distant future, there might be a massive spike in ridership to justify it. The Sheppard subway is one of the legacies of your way of thinking, but clearly many of our councillors haven't smartened up at all after that white elephant transit line. Projected ridership (2031) has shown that the passenger volumes are far below the threshold that necessitates grade-separated transit west of Jane, therefore the city came to the reasonable conclusion that the Richview lands are not needed. So instead of maintaining a bunch of wind-swepped grassy fields for eternity, why not develop it and add some moderate density near a rapid transit line, while revitalizing a suburban road.
So don't worry, I think the future is much brighter despite some people's pessimism. And if the need for grade separation ever arises by the time the LRT reaches the end of it's design life in 30 years, then a new elevated structure can be build on the ROW in the middle of the road.
At best you will save just a couple of minutes by elevating the line. The blocks are quite long here and intersections are far apart. If speed were to be the main priority, removing some of the intermediate stops would do more to save travel time than elevating the line. Personal anecdote: my friend's experience with the Eglinton bus when he used to commute to Mississauga, is that the bus runs quite fast within Etobicoke and it's mostly empty. It's a big contrast to the situation east of Weston Rd.
Here's the complete picture.

The numbers here are significantly less than the peak ridership for Finch or Sheppard LRT which will both be non-grade separated. On Eglinton, the maximum is 5400 somewhere in the tunnelled section.
