Nope. It treats ALL gun owners the same by a single data point, that they own a gun. There is so much variance in safety from one location to another, the types of company one keeps, the violence where they live vs. other areas. It is far too broad, one very over generalizing statistic.
Which is exactly how policy works, and the only way that meaningful policy works. You're arguing to create gun owners as this super special class of people that need to handled differently from all other classifications of people when it comes to directing policy with meaningful data, and there is no factual or reasonable justification for doing so.
If it's about safety and potential to reduce harm, then you would make the same argument, for example, against standardized BAC when it comes to DUI enforcement: standardizing BAC is meaningless, because literally every single person metabolizes alcohol at different rates, based on weight, tolerance, food in their system. And even so, one with x BAC could certainly be more capable of operating a vehicle than other with the same BAC, simply due to experience. But we don't tolerate that because we recognize that this is dangerous and intolerable behavior in society.
Standards exist for a reason: safety and efficiency. You can't possibly pick and choose which special snowflake classes of people get to skirt certain laws and deserve special treatment. Hell, it expands government in terms of properly enforcing these regulations, and I know we don't want that.
