I can think of two answers that have fewer open ends, though I don’t know if they are valid physics, i am sadly lacking in that area.
The bigger a spontaneous blob is the more stable it is. The only reason it should vanish into thermal noise once it comes into existence would be the same as would cause any other object to disintegrate. So, a spontaneous copy of me? Dead in seconds. Earth? All observers die in a day or so, rock stays around indefinitely. Galaxy? Cluster? Possibly pretty stable if nothing else is nearby.
If reality is a superposition of all waveforms, would that perhaps repeat at some very low frequency?
