In many research-intensive products go-to-market costs are bigger than the cost of actual invention. You buy a pharma startup for a few million for their patents, then spend tens of millions on certification, trials and manufacturing pipelines. Your competitors would spend most of that too on the same markets. Also, true inventions are rare. A lot of stuff that is being patented is just effort spent, that a lot of people could reproduce (and routinely reproduce, then hit the patent and spend more time to find a workaround).

This sounds like it is working as intended. The patent comes early in the process to protect all the commercialization investment. Patents are intended to be filed early in the process, and they gain value as the invention proves its worth. Note also that you can patent a mining claim before pulling a single precious gem or mineral out of the ground.

Well, the way you describe it, they protect investors, not inventors. Investors do not need protection. Money are abundant, market can solve the commercialization part efficiently.
