Thanks OP, I've just gone through Adam's feed.
Further down the line, he does state the new powers are the most powerful, possibly ever.
While there will be a mass of mitigating circumstances for people to challenge and there are some wonky edges such as you've quoted of Adam's, what stands out is the 'forcibly returned to your place of residence' Difficult for those experiencing street homelessness as it shows in the exemptions.
As an example, someone nips to their local shop, forgets a pint of milk, goes home and then leaves their home again to go to the shop for the milk, I'd see that being a reasonable excuse.
All of this aside, these are extreme powers that carry penalties and for some, a £60 fine (£30 if paid in 14 days) might not appear too harsh. Nevertheless, they should not be taken lightly.
