Don't know what point you're trying to make.
Total horseshit. You do not need to be colonised to benefit from the ideas and technologies of other cultures. The MRI was not invented by a New Zealander or Briton, nor was the plane, the car, countless other inventions and ideas. Most of these things arrived here through trade and cultural exchange. It is totally unnecessary to colonise a country for it to benefit from these things. Framing colonisation as something that was necessary to improve a country or people is pure rationalisation/justification of a crime.
