Using light rail as a modern day street car is just dumb. Use a street car (if it will be tolerated) or use a bus.

I suppose the problem is the ambiguity that can be attached to what constitutes light rail and street car and where you draw the line to what the difference is. I mean this both on a general level and from your particular perspecitve. So even when you state the above, it's difficult to really understand, as a streetcar can easily be perceived as another form of light rail, which it often technically is as you've stated. Hence, when you say it is dumb, it's a little confusing as to what exactly is the dumb part. In one way, you are saying "using light rail as a modern day street car is dumb. Use
light rail (if it will be tolerated) or use a bus"
So the distinction is unclear. Perhaps a modern street car or tram is one that doesn't use fixed axles? Or perhaps the intent is more so to state that using rail transit in a ROW category C is dumb, use a bus for that and keep rail transit to ROW B or ROW A?
Either way, the point is still not really true. If a street going light rail system - a streetcar - is being heavily utilized, it by and large necessarily means that it has gotten some people out of their cars. Sure a decent proportion could be users who might have otherwise walked or cycled. However, if the context (as I think you have so set forth) is bringing people from outer areas to to main employment hubs (presumably downtown,) then I'd have to agree - a streetcar is not going to be the mode of choice to most effectively do this and get people out of their vehicles. Not that this is broadly true either, but in Calgary's case, very likely to be so.
Thus, this is precisely why a streetcar is more adept at providing attractive service in more urbanized/central areas, and yeah, they have the ability to be a further urban development generator - and bringing it back to the original conversation about increasing services within the inner city, why such an option might also want to be included in a 30 year "technology neutral" plan.
Of interest might also be that the most street going light rail system when remaining in the North American context, is also the most utilized one, as already mentioned by Fusili - the TTC. This may indeed point to the value of network effects over discrete, disconnected corridors with high speeds. Zurich is perhaps a more convincing substantiator of this.
So without a specific example it is kind of hard to grasp which system or what is making a certain streetcar system unsuccessful, especially when broadly stated.
