I think if you're main concern about Brexit was that you wanted the UK to not be in the EU then you have good reason to feel satisfied.
People that voted Leave because they were upset over the UK fishing industry, farming industry, regional inequality, irregular migration etc all saw those things get worse as a direct result of Brexit. And it severely damaged the economy/growth making people poorer. Garage wasn't solely responsible for that. But he was a big voice and a key influencer
He also persistently said before the vote that leaving the EU wouldn't mean leaving all trade deals/a hard Brexit. As soon as Leave won he did a heel turn and started campaigning for a Hard Brexit..when days earlier he was calling people who were earning of a hard Brexit "project fear"
Normally when a politician/campaigner promises something and the opposite happens people lose faith in them. Farage is able to leverage dissatisfaction at issues he helped cause to portray himself as the only one who can help.
He also inserts himself into.difficult moments/issues and makes it all about him as the mouthpiece for "what people want". Which actually makes it harder for people directly impacted to talk about the issue in their own words. That's also the medias fault though.
Again it's like a known arsonist insisting they are the only one who can deal with all the forest fires.
