I did not down vote it, but I would assume that it is because the comment has no sustenance, just claiming they will be overcome offers no proof that they will be overcome. I could claim that they wont, and it would be just as valid of a statement. At the moment we don't know how they will be overcome. All proposals on the table either lead to possible centralization or still don't increase the transaction volume enough for blockchain tech to become a truly global currency that can handle all payment transactions happening in the world at any moment. While I agree it will most likely be overcome in time, I can offer no proof of that, so my opinion has very little value in the context of this conversation.
