drkodos, the conclusion that immediate forfeit is right doesn't follow from your premises:

Across the board, being late at amateur events results in a forfeit, whether it is an Equestrian event, the Monopoly Championships in Atlantic City, or Nine-ball at the local saloon.  
 So? Chess (and poker?) has a different practice. It doesn't follow that the chess version is wrong. Personally I am happy with it.

Being late is purely a manifestation of selfish and controlling behavior.   
 No, being late is usually a manifestation of poor planning and organizing skills. People with this problem are often very well aware of it, and insulting accusations of being "selfish" and "controlling" really doesn't help.

If a flat tire makes one late, that person was ill prepared to begin with, pehaps giving the chance of a flat tire happening too little concern in their planning.  They need a good course in time management, for sure.  Either way, it is the flat-tire sufferer's responsibilty, not the tournament director, or the opponents who did what they needed to do to arrive on time. 
 
 ... so the solution is to punish the flat-tire sufferer, his team mates (if any), the spectators (if any), 
and his opponent who doesn't get to play even if he wants to. Brilliant.  
Why is it more important to punish those with poor time managment than to get a game played? I think your priorities are wrong here.
