Nonsense. If Apple can offer a choice of 2 keyboard sizes, mouse and/or trackpad at discounted prices when you buy a £1300 iMac, they can offer a choice of no charger/basic charger (free)/fast charger (£extra) when you buy a £1600 MacBook.Sure, it sounds trivial, but it would force 2 configuration options to stock and ship for each unique product offering (size, memory, etc). That effectively doubles the number of products they need to carry.
Apple - and every other retailer - already stock and sell chargers separately. Ask the nice person behind the counter, tick the box on the online order form and they give/send you a charger as well. I'm sure the logistics will cost Apple pennies... and if you can't upsell enough customers to more expensive chargers with bells and whistles then you fail retail forever.
That may have been harder back in the bad old days when every different model of computer needed a unique model of charger - but this is part of the point of the whole common charger thing: Any generic charger with the appropriate power capacity will do the job. In fact, Apple offer several different models of suitable charger (inc. some 'approved' third party ones) that you might want to choose instead of the basic, non-fast-charging one they used to bundle - if e.g. you preferred a multi-port charger, fast charging, one with international mains plugs, a docking station etc.
Some of those basic bundled chargers are probably already going straight-to-landfill when customers buy a better charger.
If Apple want to sell complex, high-value products with the same logistics costs as selling bottles of water, that's on Apple. The EU scheme is sensible and should help stop companies gouging for proprietary power supplies whether or not it actually cuts waste. If Apple choose "malicious compliance" and don't pass on the savings to the customer or offering them a free charger, that's on Apple.
