Yes.

If you are actually trying to hide something from a targeted government attack, you certainly don't want to use any hosted services like Google's.

If, however, you are merely trying to avoid the government passively sweeping up all of your data, searching through it, and maybe subjecting it to further scrutiny due to it containing the wrong keyword, it helps to know that it's encrypted in transit, and that in order to decrypt it, someone has to actually present a warrant to Google.

Of course, there's the additional problem of National Security Letters, as they aren't really real warrants and they have the secrecy around them.

These problems can be attacked on multiple fronts. We can improve cryptographic security, and work on more decentralized approaches to online services, and reign in the NSA's power at a legal level, and so on.
