The situation's essentially the same in the UK (EU?) due to it being a protected characteristic under the Equality Act.

You can't say 'well disabled people aren't the target demographic, so no I don't have a ramp' any more than you can say 'whites only'.

The other commenter didn't claim it was a moral (as opposed to statutory) right, but even if that was the intention, I think that's a reasonable position to take and argue for, even if others disagree.
