They seem two different things to me, but it that were true, then it works the other way around too: anyone in favor of a VIP system should also be in favor of walking
But, just to clarify: I am not in favor of walking, I think it would be better if that doesn't exists.
However:
- since the system is as it is, I cannot see anything unhetical in doing it. Refusing to do it just puts you at disadvantage
- I think it is just a marginal problem, having a much smaller impact than it is described here
- any change in the DVC system aimed to remove walking with an impact to all members who never have and never will walk is a very bad idea
