ADS on your web page: Internet age Racket or Slavery?

OK, here is the plan -

at first, start some site that host contentfor other people.
get money, buy some computes and bandwidth and go on...

now, get some affiliates and cross promotion going on...
sell that to advertisers: hey, i've got this site it's popular and everyone is going to get your ad... cool?

But the person who is hosting the page is naturally wants to GET RID of ADS. But hosting provider that ask to be paid for that!

OK, I agree to pay and have my site cleared from annoyance of the ADS, selected by hosting provider.

So the question is how much money are made off serving ADS on NON-COMMERCIAL (a.k.a. private) pages? It seem to me that the whole concept of ADS ON PERSONAL WEB PAGES is bogus and invented by hosting providers to extract money from customers. I have ads on this page and those are absolutely off the topic... and by the those ads are from google AdWords and placed inside an ugly frame...
