These claims are not supported by quantum mechanics. The third one is certainly wrong, at least as stated. When digging into geological layers that are millions of years old, relics of an ancient past are found, which certainly have not disintegrated, although no one has "observed" them for a very long time... On the other hand, if you wait long enough, all physical structures at some point will disintegrate…
Otherwise, for the other two claims, they might be true, in some specific sense, but the quantum observer effect cannot be used to support them. They speak of possibilities that modern physics has never studied. Maybe one day, there will be a science interested in also investigating what you mention, as a possibility, but for the time being we are very far from that (IMHO).
All the best with your article.
