You have to take the mark of the beast if you want to buy or sell. That is clearly threatened and supposedly it has gone into effect in NYC but they won't actually enforce it until Sept 13. So yes, it can be both "leading up to" the MOB and also the MOB. Not only so but no one is chopping off heads of people who won't get the MOB, not yet, they are making concentration camps to house them first.If someones post-tribulation then the beast,mark ect. can be here now. If someone is pre-tribulation then this is "leading up to..." but it cant be the mark yet because their suppose to be raptured "before it takes place". "if someones preterist it was in the past(ad70) so there's no mark to be taken in the modern days ect.ect. ect. people are perceiving whats taking place currently dependent on how they believe prophecy is unfolding.
So after Sept 13 you may have a point, but not today.
