There is no guarantee that the EU will actually implement anything in the agreement with David Cameron. The wording is clear enough but with no specifics about how or when the administrative burden will be lowered. Yes the UK may be fighting to create a more business friendly Europe but more important however is the way that the EU increases the regulatory burden on the UK. This regulatory burden can be much easier done away with by leaving the EU than by negotiating reductions with the rest of the Union.
