The classic "strong above the waist, paralyzed from the waist down" image of a wheelchair user that people might have from eg the paralympics is the minority.
Would there be some resistance from some subset of disabled people to be forced to use exoskeletons in place of wheelchairs if we decided to go this route?
You'll have gazillion of small companies, many of them fly-by-night scams, borrowing money from banks and investors and spending a chunk of it on marketing exoskeletons as mobility products. This will gradually start shifting real demand, leading to manufacturers and large health providers getting increasingly involved. Doctors might start being offered kickbacks; private healthcare clinics surely will. Exoskeletons will start showing up as an available option, and will benefit from persistent marketing and generic funding - all while regular wheelchairs become less popular and, thanks to reduced demand, more expensive.
Eventually, most people will opt for getting an exoskeleton instead of a wheelchair, without, at any point, being "told what they have to do". This is the truth about modern markets in general: consumers, at scale, don't have much agency. They'll just buy whatever they feel is best for them.
