The threat of any civil unrest will be as a consequence of the way our government has failed to prepare and organise
I agree with this. All (major) parties agreed to honour the vote, even though it was just advisory. Having done so, the government should have put every effort into planning departure from the EU and discussed with the EU a possible mutually acceptable approach.
Instead, May went ahead and invoked Article 50 with no plan whatsoever and a shambolic team of politicians with no proven ability to deliver anything. There were no designs or requirements documented to set out how transport, borders, trade etc. would be handled. No impact assessments on health, education, industry etc were carried out. With the clock ticking, politicians have spent more time and effort on promoting their own selfish interests.
We are where we are due solely to the arrogance, ignorance and ineptitude of politicians, so it's hardly surprising that some thought is being given to the implications of the chaotic past 2 years.
