So I'm not sure I'd agree the point is "a fairly standard one". Some will say it was about representation, some will say it was about sovereignty, some will say it was about immigration. Some will even say it was simply a protest against the status quo.
Anyone who states "this is what we voted for" has decided that their reason for voting yes was the primary reason for 17m to vote yes, with no evidence at all.
I don't think there was a bus about bureaucracy.

If it's fairly standard I should be able to find at least one survey mentioning it online, right? I tried before sending that comment and couldn't find a single one pointing out corruption and bureaucracy as main reasons. (Or even at all) Ironically I find only articles about corruption in Vote Leave campaign. If it's that standard opinion, please post any source which ranks it against other reasons.
There are lots of contexts in which we can say we would like to see more data. However, when someone is making a point which is a fairly standard one in the Brexit debates we don't need "references". Nor would referring to an article that said the same thing as OP somehow validate the point. There is a place for asking for references, but on a basic comment like this there is not.
Based on the other comments, it seems people are more upset about the perspective behind this idea rather than its truthfulness. I don't agree with the perspective that leaving the EU is a good thing but it is uncontrovertible that a significant portion of the population in the UK agrees with OP's statement.
