Maveric149 sez:

If we do go (or already are) "invariant free" this may have the side-effect of reducing the amount of external text's we can obtain (esp. from many governments and most US states). Many times all the author/owner of external text requires is recognition for their work -- which isn't possible to ensure without an invariant section. But then, Axel is right in stating that there are larger issues at stake than making our job of creating new articles easier.

But we are recognising their work. They often don't require that people copying from us (or, even editing our work) need to recognise their work. Is there a problem here?

The edit problem could be remedied by having invariant sections per article: but this is likely to be abused. Someone will put in an invariant section with a porn ad.
