I'm surprised to learn they are expensive in the UK. Maybe because they are little known and so, low demand? They certainly aren't expensive to produce.
Here they are towards the upper end of green vegetable prices, but I don't think anyone would call them "expensive". About the equivalent of ₤1.40 for 400 grams today. For others elsewhere, that's about $1.90 USD.
Demand is probably the largest factor as you say, but then again I don't see a lot of UK produced garlic on the shelves (it's mostly Spanish if memory serves) and scapes don't seem like they'd travel well, so I'd speculate there's a supply issue on top of that.
ETA: The Garlic Farm on the Isle of Wight seems to be the only, or one of the only commercial producers (IoW has a micro-climate which is suited to growing it) in the UK, although you can buy bulbs to plant at home
