I would agree that the government does want us to sacrifice certain rights and freedoms for feeling safe. However, I don't think that saying we have almost no freedom left in our own homes is anywhere near accurate. We are allowed to do an awful wide variety of activities in our homes and in the streets. I don't think there is a blanket statement that answers the question "is it worth it?" It depends on what we mean in a given case. For example, if we are to give up the right to know what crime we are charged with when being arrested, then I would find such a policy difficult to justify. If I am meant to go through a screening at an airport to feel safe, then possibly I could be persuaded that it is worth it.
