Because the studies compare:

-Extreme Deficiency

with

-Recommended consumption

and then somehow people come to the conclusion:

-More than the recommended amount is ideal. Particularly to an extremely excessive degree.

That is the problem with most people’s interpretations of the studies. It is like the fish oil studies that show EPA and DHA to be tremendous, but then people go and recommend >20g of fish oil a day and people start to have severe immune system disturbances because of the excess consumption.

Studies have also examined what are thought to be optimal levels of serum D (e.g. 30-50 ng/dl depending on who you read). Those levels are generally NOT achievable with intakes of the DRI and many are suggesting an increase in the DRI to much higher levels (e.g. 800 IU/day to 2000 IU/day).

It’s not all deficiency stuff being misinterpreted as you suggest above.
