Any government could be spying on you. The CIA has various rules about the restricted circumstances under which it can spy on US citizens, but MI5 doesn't, nor does ASIS or CSIS or the DGSE or whatever the KGB is called nowadays or whatever the Chinese equivalent is or... well, any other damn spy service in the world. If you're a US citizen then there's dozens of countries which could be spying on you at any given time, and one that can only do so under certain circumstances.
Think it's unlikely that the French secret service want to spy on you? Think they probably have better things to do? Yeah, so does the CIA.
Oh, and let's not forget that the police and FBI could be spying on you too. Sure, they need a warrant. But convincing a judge that you need a warrant is surely no more effort than convincing your superiors at the CIA that it's worth devoting effort to spying on this random dude.
In conclusion, this guy has weird, single-target paranoia.
edit: Also, afaik, none of the stuff he's talking about is actually in the Patriot Act. That's why it was controversial when the warrantless wiretapping scheme was revealed, because it was both secret and not specifically authorized by any law.
