But you can't get rid of the NSA when there are real threats in the world. It's just not going to happen, because there actually are real threats (the number is debatable), and the existence of more than an anomaly of threats will always be justification for NSA and their ilk.
The only way to get rid of the NSA is to get rid of the threats. The most effective long term way is to work for and achieve a much higher level of peace, tolerance and community than the world currently has.

Sure you can. The existence of real threats does not mean that the NSA is the only means of dealing with them, nor even that it is an effective way of dealing with them even before considering the negative impacts it has, nor, finally -- and this is the key consideration -- that it is a net positive considering the benefits it provides against the threats against the direct threat it produces to freedom.
I'll concede that getting rid of the NSA regardless of threats is within the realm of possibility. But it's very unlikely. Maybe more unlikely than world peace.
