Strongly disagree. There are so many situations in which abusive people (employers, romantic partners, politicians) need to be caught unaware or they won't be caught at all.

Obviously there are lines to be drawn when we are talking about the government recording citizens. Warrants are an important check on power for this. But any individual should be able to record (mostly) anything. At the very least, it can save you money when a customer service rep claims they never said something. At most, it can keep you out of prison.
