The argument that people will use whatever is at hand is fucking stupid. Its a lot more difficult to kill someone with a knife or bow than a gun. In many cases, the target can flee or sustains a non life threatening injury. Guns relative to other weapons are incredibly efficient and ending life.
here is a citation that shows owning a gun doesn't protect you (which I am sure you will find a way to dismiss):

Results. After adjustment, individuals in possession of a gun were 4.46 (P<.05) times more likely to be shot in an assault than those not in possession. Among gun assaults where the victim had at least some chance to resist, this adjusted odds ratio increased to 5.45 (P<.05).
Conclusions. On average, guns did not protect those who possessed them from being shot in an assault. Although successful defensive gun uses occur each year, the probability of success may be low for civilian gun users in urban areas. Such users should reconsider their possession of guns or, at least, understand that regular possession necessitates careful safety countermeasures.
