There's an idea going around that someone in a wheelchair is useless, only to be pushed on and off the boat. Just maybe, they might like to try doing a bit more, whatever they are capable of trying or doing. Taller bollards assist with this. Having worked with people with disabilities they know what they might like to try or be capable of, they may need support and encouragement. Or not, let them get on with it.
