I think blocking the corral with a goal is a totally valid way of playing the game. It is a very valid strategy, and has lead to the victory and success of many teams at many of the regionals. It is an aspect of the game that can greatly reduce one teams scoring potential thus leading to an edge. I don't see anyhting wrong with that strategy at all. It is fair and not against the rules, so why not do it? It would be like saying don't get on the bar and spread some wings (if you had them) to prevent other teams from latching on to the bar. It's fair and valid and a good strategy if played out properly.
