The technology exists to trivially encrypt your data if you want to. That's not a product most people want, because the vast majority of people (1) will forget their password and don't want to lose their data, and (2) aren't particularly worried about the feds barging in and taking their laptop during a criminal investigation.
That's not what the idealists want, but that's the way the market works. When the state has a warrant, and you've got a backdoor, you're going to need to give the state the keys to the backdoor.
