This theory explains a lot of the unknowns by the narrow focus of spike pathology theory, which shouldn't be downplayed, but it doesn't tell the full story.
The IV injection of LNP:s seems to be the main culprit, which spreads this material all over the body and causing all of this initial endothelial damage, leaks the material into various organs from the blood stream, and then spikes are being transfected, triggering possible secondary damage over months, and years to come.
These theories are compatible and together, tells a larger story.
