There are settings where you can trust the local machine but cannot perform any installs. In many offices normal users do not have the technical or formal permissions to install software, even though they may trust the local machine to not be infected by malware or be compromised in some other way. Another example may be if you are only allowed to access the internet through a proxy browser solution using e.g. Citrix MetaFrame, then even though you might be able to install applications locally, they will not be able to connect to the internet directly.
