Working remotely in the UK from the US?

This sub seems to be very anti remote work for reasons I'm not sure about. This reply of mine, for example, was just downvoted without any comments about why it's wrong. There is also one legal precedent, Matter of Hira, where remote work from within the US was considered legal. However, redditors here tend to interpret the law in a way that says any work is forbidden. One person even said that if I tell a border agent I will be reading my work emails on ESTA they will bar me from entry (which is of course ridiculous).
