The New Covent Garden Market itself is currently in the middle of a multi-decade redevelopment, they've slightly reduced the footprint and sold off some land for development, and the remains (still a massive area) is being _very_ slowly converted into a more modern design - sadly not really a market where you can actually go on foot to buy things, but a co-location area for lots of wholesalers to warehouse and deliver from.
The TV license is certainly bit ridiculous, but being legally blind doesn't necessarily mean you can't see at all, just you fall below the legal threshold where it's judged that poor sight will interfere with your day-to-day life. Lots of people registered as blind can still watch the TV just fine even if they won't be able to see the detail.
