Firstly, you CANNOT skip an element in multiplication. If v= -1, would you skip it too because it doesn't exist? That's nonsense. You can't do that.
Secondly, m*v=P, v=0, means that P=0, meaning m*v=0, not m=0, IOW, v being equal to zero has nothing to say about the value of m in m*v.
And you said it yourself, if the velocity is zero the momentum is zero, not the mass, but the momentum is mass multiplied by velocity. The rest of your post is nonsensical and doesn't follow.
In short, that's not how multiplication works
