As I said, when you meet with them off of the forum they admit they are not as dogmatic about their investments, or their lifestyles. (really, if they all followed a 1/3 US, 1/3 int'l, 1/3 bonds they wouldn't need meets or conferences--what would they talk about?) The feeling I get is that they feel for the novice investor (especially the typical BH noob who's got a fair amount of money to invest), the safest advice to give is the standard BH advice--LBYM, max tax-deferred options, use the standard three- or four-pronged approach to index investing, and try and retire in your late 50s with no mortgage. Honestly, most people can't even manage that so for most people it's good advice.
It's the same with ERE. You don't start by telling them to give up the cell phone. You start with the standard advice--cut the big three and then put as much money away as possible. It can't hurt anything and most people won't get past that advice anyway.
@jacob--I remember that thread about you. Wasn't it right when you went back to work? IIRC it was pretty vicious, even attacking DW, so I understand why you're not a fan
