Banning research funding is a decidedly more political act. One that people don’t have the opportunity to cut through.

Also as an aside your point about existing data not correlating with homicide rates is particularly non compelling because it doesn’t normalize for firearm kind (handguns are more likely to be used in homicides than other forms of firearm) nor victim type (firearm ownership is massively correlated with domestic murders) statistical collection bias (the Las Vegas mass shooting was not included in national homicide statistics) or the massive scale difference of the US vs the rest of the world (we have a lot more murders of all type).

But here is the thing bad data is _easier_ to manipulate. Every good actor should be cheering expanded research into this issue because it gives all of us a better framework to reason from.
