Privacy On The Internet - A Contradiction

Many times I have mentioned one of the more technically oriented info services that I am subscribed to. On that blog I found an IMHO good article about privacy on the internet or, better, the lack thereof. The article is here. I will quote it literally because of a comment I want to add.
  1. There is no such thing as 100% privacy on the Internet.
    You can take steps to lessen the intrusions into your privacy but there is no way to guarantee that nothing can be learned about you and your affairs. Learn to live with this reality and act accordingly.
  2. Like it or not, you have to trust somebody.
    Anything you do on the Internet has to go through numerous intermediaries, routers, networks, etc. Ultimately, you have to trust the security of your ISP and other services that you use.  VPNs and proxy servers can increase your security but they are not foolproof. 
  3. Privacy comes at the cost of convenience.
    The more measures to increase privacy that you use, the more cumbersome using the Internet becomes. Locked doors are harder to use than open ones. The correct trade-off between privacy measures and convenience depends on how you use the Internet. If you like to live dangerously, you may need a lot of privacy measures. If you are a casual web surfer and send harmless emails, not so much. Choose the level of privacy appropriate to your Internet usage.
  4. There are innumerable ways to spy on wireless or cell connections.
    There is no standard encryption that can’t be broken and deciphered but using a strong version of WPA encryption on your wireless router is better than not. Avoid using public hot-spots for private business.
  5. Assume that all email that you send is public.
    If you must use email to send sensitive material, use some form of strong encryption. Send the encryption key to the recipient by some other means than email.
  6. Deleted email is probably still there somewhere.
    You may delete an embarrassing or private email but it may very well still be on the email servers or on the other party's computer.
  7. Everything you do or say on the Internet is recorded somewhere, usually in numerous places.
    You can take measures to make it hard to trace your Internet actions back to you personally but there is always the chance that a persistent and technically adept person or agency can track you down. However, most of us aren't important enough to warrant that kind of effort.
  8. What you post on social sites might as well be on a public bulletin board.
    Privacy measures at Facebook and other social sites are full of holes. Assume that anybody can see what you post.
  9. Be careful what you reveal on the Internet
    Use disposable email addresses and pseudonyms as much as possible. Don't reveal anything you don't have to when signing up for some service. Assume any information you reveal on one site gets shared or sold.
  10. It is almost impossible to remove all traces of something once it is on the Internet.
    Those pictures of yourself that you posted when drunk can come back to haunt you years later.
  11. Advertisers want to track you.
    Advertisers want to know as much as possible about your activities so they can target their ads for you. They keep developing more and better methods to track your Internet activities. Gizmo’s has many articles about ad blocking and control of tracking cookies. 
  12. Monitor your credit cards and bank accounts daily.
    Personal records stored in company databases are stolen all the time. If you have online credit card accounts, monitor them for unauthorized activity daily. Also monitor any online banking or financial accounts daily.
Especially to points numbers 7 through 10 I want to add: Everything you ever put out on the internet will never go away. Clever sleuthing will bring it to the light of the day no matter how firmly you believe that "deleted" items or accounts should be gone for good. Usually they are not gone, you just can't access them anymore.

As usual I welcome suggestions and comments right here in the blog.
