Fortunately, for the Goldson on Doucet hit, that didn't happen, but I could see how a similar situation could arise and then lead to the perversity that receivers make themselves unnecessary victims.
I also see what you mean by the hard form tackle perhaps being preferable. Tangentially related to that, I have to say that the celebratory behavior of Goldson afterwards was classless. Still, he did carry out the primary responsibility in that situation for a defender, which is to administer enough force cleanly on the receiver to make it very difficult for the receiver to complete the reception. A hard form tackle could have done the same thing.
Here's the easy answer to this. If you form tackle, you're probably not going to get flagged. That goes for defenseless receivers too. That goes for unintentional helmet-to-helmet. Anytime you missile yourself into a defender with your helmet or with a lead shoulder (vs. your shoulders), you have no reason to complain even if your intention was to go after the torso or chest. You might accidentally go too high or your offensive guy you're trying to hit might go too low.
It's why I have no problems with flagging and penalizing these hits. If you want to stop getting flagged, then stop missiling yourself into players.
