Is this argument valid and sound? Logics?

[Fah King]

the argument is sound, but not valid

7&8 are "value judgements" based on your personal opinion. They are not "truths" from which a valid argument can be constructed. I could argue that there is SOME benefit to lowering productivity or wasting time... reduced stress, less chance of a heart attack, more "pleasure", increased "quality" of life vs less "quantity" of productivity. Compromised privacy is a tougher nut, but lets say from the Governments or the FBI's standpoint there is some benefit to National Security. Terrorists socially network too.

if we "accept" all your argumets as "truth" then the argument is indeed sound... but once we examine the "value" of the individual arguments, some of them are invalid
