tl:dw The video points out even after druids, paladins, and then later death knights and monks became viable tank options, and even after the introduction of dual spec, there was and will always be a shortage of tanks in dungeons. Taunt won't fix the problem.
You're right that the problem can't be solved, but it can be helped and mitigated, if only slightly. Blizz changes definitely did mitigate the issue a fair amount, which is better than nothing. There is no argument as to why not help mitigate the problem in small ways.
It doesnt even have to be extreme like a taunt, more along the lines of making consecration generate 20% more aggro, etc. Minor things.
