Leaving your Tank Stance while Tanking...

1. Makes Threat more difficult to keep
2. Makes you less effective at not dying
3. Increases stress on the party and thus makes them less able to perform their roles efficiently
4. Increases the overall difficulty of the fight

It's not terribly tank-like at all. The OP appears to believe that the ability for Tanks to be so untank-like yet still clear content is an issue. Which it is. But, the stances aren't exactly the root of that particular problem. It's that content has inexplicably stopped attempting to severely challenge a Tank's ability to mitigate attacks. As I said in my reply earlier, there was once a time when Tanks were challenged enough in these respects that Tank Stances were much more necessary. This is no longer the case.
Three and four you literally made up. Stop being sneaky you!

The idea of having 'leadership' thrust upon them is one of the reasons tanking is so unappealing to people in the first place.
