You should really consider editing your question and clarifying it a
bit to make it more clear of what you are asking. Reading all the
answers you dismiss and their comments, I think what you are trying to
accomplish is to have some Component Presentations on the Page editable
and others not.
Depending on the version of SiteEdit you are using there are two solutions:
SiteEdit 2009 SP3 - You should remove the inline editing TBB from the Component Template which you do not want editable, the Page will still generate a hover-over the Component Presentation so it can be moved.
UI 2012 (the new UI or Experience Manager) - You can disable inline editing per Component Template, through the checkbox in the Component Template.
If you also need to have the hover-over on the Component Presentations removed, then I think the only solution is to remove the Inline Editing features of the Page Template (for SE 2009 SP3, remove the TBB and for UI 2012 disable it on the Page Template) and generate all the required SiteEdit marking yourself in the Page Template.
An interesting question to all this would be "why?", what is your requirement exactly to have the need for only enabling inline editing on some of the content on the Page. Since you could also accomplish that through (editing) permissions for certain user groups.
