Why is it that the main objection concerning gun control

[OneTenthofOnePercent]

5. The primary objection is that some people don't want

restrictions that will end up having little/no desired effect. Why would you want restrictions on your hobby when society has literally no real benefit?

One reason that people will focus on the technical intricacies of bans is because without understanding of WHAT is actually being banned, it is very difficult to understand the actual effect on gun crime and gun culture. So all you end up with are a bunch of restrictions and red tape that law abiding citizens end up having to jump through hoops to obey, but at the end of the day, it changes nothing. People don't necessarily like limitations on their freedom and more laws to follow... and they like them even less when no social benefit is gained for the additional restrictions. For example, the old assault weapons ban (1994 AWB) certainly had alot of restrictions (that effected people who cared to obey them), but in the end it was doomed to fail in effecting actual crime rates because:

a) Assault weapons actually make up VERY little crime. Even successfully eliminating assault weapons and high capacity mags from public couldn't have decreased gun crime by more than 1-2%. Such a measure wouldn't even avert most mass shootings because most of them use handguns, non military style rifles, and shotguns.
b) The fact that a gun has a high/low capaity mag isn't nearly as beneficial to firepower as the ability to change mags in about 2 seconds. Shooting a 30 round mag in "X" seconds and shooting three 10 round mag in "X+6" seconds is effectively the same thing.

Someone with a technical understanding of how these things (semiauto rifles) work could have seen the AWB as a HUGE failure from a mile away. In short, "control" implies knowledge and technical application of that knowledge in order to manipulate. When people question the technical aspects of legislation in addition to its supporters' technical knowledge of what they want to control, it's probably a pretty good predictor of what kind of chance the legislation has of achieving its goals.
