I would regard it as a mistake to close ticket offices at some major
stations with special requirements, like Heathrow.

Doesn't Heathrow have one of those "tourist reception" centres designed
precisely for those special requirements? Euston does.

Those places are designed to sell theatre/attractions tickets, and are
virtually nothing to do with tube ticketing.
