Curiously, when I sold a bike on fleabay last year in the depths of lockdown, anticipating only local interest, I thought a London based buyer was taking the mickey (about 180 miles away) but he arranged a courier to collect. I got an email the night before collection, and he had already paid by then. I hadn't realised the extent of the bike famine at the time, but presumably this arrangement was legal. I certainly wouldn't have considered collection/delivery of an item at that distance myself. I hope we are all more aware of the risks now.
How elastic is local? If social distancing is maintained, travel is only point to point and return with minimal interaction at the collection end and no stops on the way maybe local bike collection might be justifiable. It's not just that I'm Mr law-abiding, but that I would want to act in the spirit of protecting myself and others to the best of my ability and in good faith.
Practical factors such as having a teeny tiny bladder might further limit one's range if a stop free journey was required. It's one of those how long is a piece of string things where those who don't give two hoots for the regulations will blithely get away with things whereas others might get stopped on their first trip out. The likelihood of being stopped on a potentially unneccessary journey is an unknown and variable factor. How far can you go while out on your bike doing daily exercise? No stated limit. " Use common sense".
So do the same for your bike collection trip -act within the admittedly vague guideline of staying local, and use common sense. If in doubt, leave it out.
