It's a tricky line to walk.
On the one hand, you are absolutely right that ability to hobble over a few feet from your chair does not mean the chair is obviously not needed.
On the other, wheelchairs are a very popular prop for grifting folks.
It's pretty damn near impossible to make an informed judgement on such a matter in an instant, and lots of people do exploit that.
How relatable, being able to not care about what precisely you are buying and how much it costs and letting an AI just spend a few hundred dollars without you even knowing whatever the hell it was.
If trying to show getting a gift, way to show that thoughfulness of fobbing off the whole process to a bot.
