Paraphrasing (4th paragraph)

Text

The environment in which businesses operate is influenced by all of these. This, whereas the single currency will have the important effect of removing the barrier that is currently being imposed by different currencies, by itself it does not change much else. These currencies are simply administrative characteristics defining national economies. Although in future they will no longer exist, nothing else in this particular categoiy of differences will disappear in their wake.

The main idea of the paragraph

The currencies are just one aspect of administrative rules and standards. The adoption of a single currency does not mean that the other aspects of administrative rules and standards will automatically disappear.
