Yes, I can agree with this. So, the real truth is that any LTE
multicast/broadcast future doesn't need to offer higher spectral efficiency.
Instead, anything sent in multicast/broadcast mode only needs to be used for
content that really must be consumed in real time - live events such as games -
and the bulk of TV programming is instead best sent VOD. And for VOD, you need
a two-way RF medium.

Perhaps, during very restricted times. I think this would only apply during
sporting events. Not a huge deal for the vast majority of time.

Doubtful. For broadcasters to use LTE as required, first of all they would have
had to convince the tablet and smartphone vendors to tune into those frequency
channels. But these hardware vendors are in the pockets of the WISPs (and/or,
like Apple, are much happier making users pregnant with their own content
stores). So it seems unlikely.
Secondly, for broadcasters to deploy a reasonably cost-effective LTE
infrastructure, while still optimized for mobile, they will have considerably
less usable spectrum than the have now. Which means, they would have to rely on
VOD over the 2-way Internet, or more entirely rely on MVPDs, to get the rest of
their content out. (Probably not a big deal for MVPD addicts, but the younger
generation isn't buying into this model quite so readily.)
It would be a different ball game for broadcasters. You make it sound like it
was as easy as falling off a log.
