I think this very much depends on where one wants to fly, e.g. cities or nature. For a drone weighing 734g (Mavic Pro), under EASA rule one either - has to fly 150m away from residential, commercial or industrial areas (subcategory A3); or - is required to hold an A2 Certificate of Competence (which would allow flying close to uninvolved people but, at this weight, not over them). Qualifying for an A2 Certificate of Competence is not hard (I've done it both in the EU and the UK) but it is significantly more involved than punching a few details into a Web form.
