Ah, the old "criminals will rob you if you don't consent to have the government take your money to hand out to them" argument. Often peddled by those who also believe criminals are not responsible for their actions, they're just oppressed/had a bad childhood/whatever.
I'm fine with universal (modulo pacifists and those not capable of handling a gun) individual gun ownership. Combined with anything resembling rule of law, in that case armed robbery quickly drops off the list of "what it takes to survive", because it no longer results in long survival. The criminals will always be outnumbered.
But let's get back to the real topic. Fact is, I like libraries. I think they're very positive for everyone in many ways, in particular for being an intellectually-oriented gathering place.
New to these particular arguments, so your first sentence was perspective adding. Should have realized though that the strong libertarian bent to HN would make a lot of arguments old.
That said: In my defence, I'm neither for nor against the topic, and wasn't making the arguments you suggested I was. I was alluding to large groups of criminals overwhelming or out-gunning paid protection at some point of the scale.
As you said, lets get back to the real topic - libraries are great. Although it did seem like computer education and literacy was one of the major draws - perhaps people here could help by helping an NGO which provided volunteers to help people fill forms up or give them computer education?
