Yes of course that was a bad example.
What about a free newspaper, like those distributed in the subway?
I can rip off all ads before reading it, once it's in my hands I can do whatever I like with it (apart from copying and distributing the articles, that's not permited of course).
I have not bought and paid the webpage I'm viewing, my browser requested the content at an address, and the web server sent me the content. For free. Now that this content is on my computer, I can do what I like with it. I can delete it in part or in whole, I can choose to display any part of it on my browser, I can save it to read it later, I can look at the source code, I can display it using my own CSS to alter how it's looking...
It's MY computer, that I bought myself. I'm the administrator on this computer, I can choose what I want to display, what code I want to execute, what files I want to delete, save, alter, etc.
Now if they want to have total control on how the page is displayed, they're welcome to lend me a computer where they are the administrator, they use their electricity, and their internet connections.
I pay for my hardware and ressources, I'm the only one who can decide how they're used.
My computer is private property, the processor, RAM and storage space is part of my private domain, nobody can decide what's going on in my house as long as I obay all laws.
So, like you said, if the content creator or distributor doesn't want me to display the content like I want, their only option is NOT to send it to my computer. I have no problem with that, it's not like I will miss it.
