I think I see where you're coming from.  I think the logical conclusion is this:  Don't bother staying healthy because we're all going to die anyway.  Don't bother learning anything because we're all going to die anyway.  Don't bother helping to make the world a better place because we're all going to die anyway.

You know what?  I don't care if I'm going to die, or if most people won't benefit from the things I do.  I am going to live a while longer, and some people will benefit from what I do, so I'm going to do it and encourage others to do it.

I haven't bought guns, and I may have gone to one gun show.  But about the cash - Yes it does!  So the gun retailer can drive the cash (or mail it?) to the gun manufacturers.  Most of them use checks and credit cards though, and such instruments require banks = susceptible to choke points.  Cash is great, but virtual cash has its advantages too.

Thanks for the opportunity you gave me to explain some of the finer details of my understanding of what makes bitcoin valuable and useful.  Do you have more denigration of my idea for me to take a swing at?
