It's an analogy. In this case, 'advertising' = hauling. There are different aspects of an overarching effort; not everything is smashing into other players until one of you falls over. Not everything SHOULD be that way.
Then you fail to understand my point. If everyone plays like you do, Powerplay is one dimensional racing. PvP would act as a filter making that hauling more difficult. This in turn means powers can't rely on 100% delivery rates, and consequently makes a large territory harder to maintain. This then ensures you never have a full bubble and that you don't have situations like now where the bubble is full and Powerplay becomes trench warfare squabbling over scraps.
I see zero ingame evidence that this is the case. Especially since most hauling takes place in neutral or allied space, where those players should theoretically be safe.
Currently there is little because modes come into play or blocking gets involved (hence this thread). If / once rules become cleaner then it becomes more important. Sandros proposals make prep sites, capitals, uncapped UM sites much more busy.
And your solution to this problem is to make things even less welcoming? The game mode needs more rewards, more incentives, not more reasons for players to avoid it entirely. Which is exactly what this suggestion would do.
Depends on what you want. You already have a fully features BGS and CGs, why does that need to be replicated again? Powerplay has to offer something the others do not, otherwise.....whats the point?
