This is some very black-and-white thinking.

If you haven't grown up with every semi-publicly spoken word recorded and made searchable, you aren't used to restrict what you say to those that you are OK with being recorded.

But, even more importantly, even if you do, you might later change your mind about things.

Part as a problem is that we, as a society, don't really deal appropriately (at least in my opinion) to old recordings. If somebody said something slightly offensive 10 years ago, and it wasn't recorded, basically nobody cares. If it was recorded, there's too much outrage, considering that this was one thing of literally 100k things they said that year.
