At 6:25 we see Kinglsey use a spell to sorta freeze time. From there it's easy to see that the Death Eaters aren't actually smoke but instead just covered in it.
It's also apparent in this:

Here we have Voldemort physically grappling with Harry. Clearly he is not intangible while using this spell.
No. At :35, one passes right through another. The second example, OK, I'll admit, the angle makes it hard to see.
Freeze time, you say? Cool. That's one more weapon the Death Eaters have.
Also, if what you say is true, then the Death Eaters can endure mad punishment while in smoke form. Examples? In the vid I posted they smashed through a stone wall with no damage. In the attack on the burrow, they smashed through the walls of the house with no damage.
Either way, while in smoke form, they are too much for the Avengers.
