"I don't mind the government watching everything I'm doing, I have nothing to hide"
You're confusing privacy with secrecy.
Your privacy is no one else's business, leaks can harm you.
Secrets and lies hide the truth, they can harm others.
What might be harmless today might be used against you in the future. If everyone knew you were the #1 person buying the most Coca Cola in your local store, when it turns out Coca Cola support Trump, people may come after you too.
If you knew the government were tracking your every moment, wouldn't you act differently?
If your data is sold off, a third party or an AI might misinterpret your innocent intentions.
Just because you think there's nothing to hide, doesn't mean you're immune to scrutiny.
