If those thirty companies reconfigure their holdings so they each own one thirtieth of each of thirty parcels, under your model all of a sudden each company has thirty votes.
I believe if you tried to exploit the ambiguity in the law in a way that mattered enough for anyone to care, you would catch a lawsuit predicated on the idea that the one entity/one vote concept was violated by this trick. I think a court would approve of the idea.
I still agree with you that this law is poor, I just don’t think this exploit flies in court. But no one knows until they try.
