A freewill conclusion

So what.

Say everything is determined, one straight line from beginning to end, no choice in the matter, all cause and effect, puppets on a string, no ultimate free will.

One conclusion is: so what. 
We can still praise and blame people for there actions.
Someone winds up and bitch smacks you. You don't care that they had no ultimate say in the matter. Nor should you.

We don't live in a world only filled with theories, ideals, and concepts; we live in a world filled with people. People who judge themselves with praise and blame. People who are guided by the praise and blameworthiness they assess to others. And people who ultimately take responsibility for their actions.

.....

I am not sure I buy this conclusion.
