We aren't obligated to buy from within the EU. Obligation means we have to when we don't have to. It may be cheaper in plenty of cases as no tariffs and far less bureaucracy (and therefore less cost) to buy in the single market but we are not legally bound to buy the EU product. As an obvious example, walk down a Supermarket wine aisle, alongside your old world wine (France, Spain, Germany etc) you will find a lot of new world wines (Australia, Chile, New Zealand, South Africa etc). We aren't obligated to buy the old world wine. You need to look up the definition of obligation.
Again, evidence for the EU being a collective economic mess?
You still haven't explained how state subsidies and these other economic tools will negate the impact of the tariffs? Or where the cash is going to come from for these subsidies and other tools after Brexit? Less "oooh, look a squirrel" by the way, far more an "Ostrich with its head in the sand".
Or how long the short term impact is going to be in your opinion? And how many years do you think it will take to mitigate the economic impact of a crash out Brexit on the UK economy? Especially with the lack of expertise and negotiator numbers to negotiate with the whole world as we will have to do.
I'm absolutely confident the US will demand lower agricultural standards in any FTA as the powerful Agricultural lobby are already putting pressure on Congress and the US would be in a far stronger negotiating position than us.
Frankly I don't care what Corbyn wants as he is useless as the Maybot. Corbyn (and Momentum) is the reason we don't have a decent opposition and with FPTP it ensures we're stuck with the rubbish of either of Labour/Tories (although the Tories far more likely). You're right that a decent opposition would be well clear of this Govt in the polls.
I also agree on the use of bribes to MPs from deprived areas. Especially as this Govt and the Tory Party were the ones who focused on austerity.
