I think you're mixing up with PIE.
The reason bindnow is disabled by default is performance:

dpkg-buildflags: Disable bind now by default
This option has a startup performance hit on slow systems, particularly
due to slow I/O, the effects of which cannot be reverted except for a
rebuild. It might make sense for long running processes where the
startup time is not that important, and the security improvements do
actually matter. Another option is to set the environment variable
LD_BIND_NOW=1 for the long running process, so that the sysadmin can
disable it if desired.
