Not going to say they didn't but those facts are not data, what are the actual numbers that they result in? Then when you have the numbers, that isn't evidence as it may not be supportive of your theory. The data would also fit a model where UK outperformed the G7 due to increased output, or a decrease in costs. So you have to find data that supports only your theory.
Currently we only have one example of a nation leaving a political union, the UK. There could have been many factors that could have caused the underperformance of our economy and without further data you can only say that it is 'in your opinion'.
they resulted in an increase in trade barriers which costs money -there hasnt been a trade benefit which outweighs the increase
you are trying to create a strawman by suggesting you cant isolate the figures nor make a comparison

Brexit trade barriers on food have cost UK billions – report
Barriers include extra paperwork at border points and veterinary checks on livestock.
Brexit trade barriers include extra paperwork to validate goods at border points and veterinary checks on livestock.
The University’s updated report on the impact of the UK’s departure from the bloc –
Brexit and Consumer Food Prices – found that trade barriers have hampered imports, pushing up household bills by an average £250.
It calculated the cost of food in the UK has increased by 25% since 2019 but if the post-Brexit trade restrictions were not in place then that would be only 17%.

Unbound: UK Trade post-Brexit
This study analyses the significant and lasting impact of the Trade and Cooperation Agreement(TCA) on UK-EU trade relations three years after Brexit. The findings reveal sharp declines inUK exports (27%) and imports (32%) with the EU between 2021 and 2023. The contraction intrade is attributed to reductions in both the variety of goods exported (33%) and the intensivemargin of imports (28%). The study highlights that the TCA has caused severe disruptions inthe UK-EU supply chain, particularly in consumer and intermediate goods. Sectoral differencessuggest that smaller EU economies have been more affected by reduced UK export varieties,while larger ones like Germany and France have seen smaller declines. Non-tariff measures(NTMs), especially in agrifood, textile and material-based manufacturing products, havesignificantly impacted exports. The study emphasizes the need for policy interventions,including mitigating the adverse effects of the TCA, reconfiguring supply chains, andsupporting firms in adapting to new trade barriers
Our baseline estimates based on monthly data indicate a 27% decline in the value ofUK exports to the EU and a 32% decline in UK imports from the EU between 2021 and 2023,compared to a counterfactual scenario without Brexit. This translates to an annual loss of $80.1billion (£64.7 billion) in exports to the EU and $145.2 billion (£117.6 billion) in imports fromthe EU as of 2023.
