If the sender does not want his/her message to be misunderstood 
because of advertisements, he/she could use a service which doesn't 
insert such content.

I doubt that advertisement is absolutely necessary for the 
development of the Internet.

If a new disposition type was defined, it might be used by some 
parties to remove that part of the content.

Advertisers tends to look for more visibility.  If it's away from 
other inline content, the advertisers won't see their message as 
being visible to their audience.  There's also the question of 
compatibility with legacy MUAs.  Defining a new disposition type 
won't solve the problem.
