Decent advice but it fails to account for the fact that the feds intercept, review and catalog all of our phone calls, emails, texts, web searches and electronic commercial transactions.
Unless one chooses to live in a cave, you're already subject to the unconstitutional surveillance dragnet that both parties have and continue to support.
You can very easily slow them down if not divert their efforts outright, FRiend. Phone calls and text messages, yes, you’re at the whim of your provider, and most of them will willing give into government requests.
You have a LOT more control over your computers, however. Until they outlaw encryption tech, they can’t read what you’re doing online without your permission.
First thing you should do is invest in a TPM (Trusted Platform Module) for your computer if your motherboard supports it. This is a digitally-fingerprinted encryption module that is as unique as a fingerprint and specific to your computer’s configuration and utilizes a hash that is so complex as to be impossible to crack without utilizing quantum computing technology not yet available.
With that TPM, you can then encrypt your hard drives or at least portions of them. I create a few encrypted “shards” on my main disks. On those shards, I keep valuable information about my identity, bank accounts, investment information, and most importantly: my browser cache.
I use Firefox, and you can set it up where your profile (e.g. browser cache) is stored on this encrypted shard. It contains every last thing about where you’ve been, what you’ve downloaded, history, bookmarks, everything. Without it being loaded, Firefox won’t even start. Without the multi-factor password and certificate hash, no one can get into it. They can arrest me and torture me until I’m dead, but only I can give them access with the information in my brain.
Invest in a digital certificate, invest in a TPM, download a password locker, and keep an encrypted thumbdrive handy for secure data. Lock that in a safe or a bank safe deposit box, and you’ll be as secure as you possibly can be without doing as you suggest and live in a cave.
