People should use stable computers and internet connections either way for their own good. By your logic we could also implement additional lag, just becouse some people are disadvantaged by playing on wireless connections that skyrocket their ping.
Some of us don't have a choice. At my home, I have a choice of Comcast or Comcast. It's craptastic. It isn't likely to change as Comcast regularly gives "dollars of free speech" to our elected officials so that there is very little chance of anything changing. I get to pay about $75/month for a connection that drops me from games completely roughly 5-10% of the time.
The game servers do have a reconnect feature that does work. I get probably 2-3 times as many reconnects as I do drops. The problem is that everything keeps playing while I'm waiting to reconnect so I often lose units while it reconnects.
If I had a wish list for COH3, it would be that the servers were more fault-tolerant. This is the only online game I have that has this level of disconnects. SC2, WC3, GW2 all disconnect much less often.
