How to prevent files extraction from an Installer created with NSIS?

When someone installs NSIS on his machine (make_machine) the binary file will be created with random order of EW_ enum.

When makensis.exe is run it reads the binary file and builds the resulting installer.

SO every NSIS installation can have different EW_ enum so it is be complicated for 7zip to unpack such generated installer.

The difficult part would be patching the exehead when compiling, after all, if we embed the EW_ file as a resource it can just be extracted...
