Michel Barnier, said the British people need to be educated about the consequences of leaving the single market?

is that because the EU failed to promote itself in the UK ?
Leaving the EU meant leaving the single market, in order to create our own market. @thatginamiller #Brexit ??????
@jennirsl @ChrisGiles_ You are very strange, 85% of people voted for parties who had leaving the single market and…
#Brexit bill: Barnier gives UK two weeks to clarify key issues - The British people need clarity as well
"Leaving the single market is what we voted for!" Err, really? #SingleMarket #Brexit
The great @Mike_Fabricant is on #FirstDates, I wonder if he'll be leaving the single market before the UK does ❤️👫

As they were breakfasting, a question of Michel's, relating to the projectile, provoked rather a curious answer from Barbicane, which is worth repeating. Michel, supposing it to be roughly stopped, while still under its formidable initial speed, wished to know what the consequences of the stoppage would have been.
To avert such a conjuncture by the restoration of peace was necessarily an object of British policy. More than that, however, was at stake. The Orders in Council had served their turn. In conjunction with Napoleon's Continental System, by the misery inflicted upon all the countries under his control, they had brought about the desperation of Russia and the resistance of the Czar, who at first had engaged in the Emperor's policy. Russia and France were at war, and it was imperative at once to redouble the pressure in the Peninsula, and to recuperate the financial strength of Great Britain, by opening every possible avenue of supply and of market to British trade, in order to bring the whole national power, economical and military, to bear effectively upon what promised to be a death struggle. The repeal of the Orders, with the consequent admission of American merchant ships to every hostile port, except such, few as might be effectively blockaded in accordance with the accepted principles of International Law, was the price offered for the preservation of peace, and for readmission to the American market, closed to British manufacturers and merchants by the Non-Importation Acts. This extension of British commerce, now loudly demanded by the British people, was an object to be accomplished by the same means that should prevent the American people from constituting themselves virtually the allies of Napoleon by going to war. Should this dreaded alternative, however, come to pass, not only would British trade again miss the market, the loss of which had already caused widespread suffering, but, in common with it, British navigation, British shipping, the chief handmaid of commerce, would be exposed in a remote quarter, most difficult to guard, to the privateering activity of a people whose aptitude for such occupation had been demonstrated in the fight for independence and the old French wars. Half a century before, in the years 1756-58, there had been fitted out in the single port of New York, for war against the French, forty-eight privateers, carrying six hundred and ninety-five guns and manned by over five thousand men.[487]
