That's not what is happening here. These tools (Neuralink and others) enable people who are disabled to participate more in society.
I'm struggling to understand your point. You seem to be saying that Musk is trying sell a product to people but at the same time taking away their ability to pay for it. Logically, that means nobody would be buying the product, which leads me to conclude the thinking you express above is flawed.
But. It also doesn't take a lot of imagination to see what other beneficial uses they promise to bear, as a general device. Imagine having a computer plugged-in permanently in your brain. Both in reading (and reacting by providing a stimulus, whatever it is, however you may do so directly or indirectly), and perhaps even, some day, in writing.
When you see what you can achieve with an individual, customised touch-screen computer in the pocket, something that didn't even exist a quarter of a century ago. The potential. The horizon. How would you not invest in that vision if you had the money for it?
What a striking coincidence that the man behind this project has now access to the resources of a huge country, which administration happens to deport "illegal" immigrants here and there, without due judiciary process (that is, publicly documented), in territories outside of judiciary overview (like Guantanamo).
The same guy who felt brazen enough to make twice a nazi salute in front of televisions.
Far fetched scenario? Yes, obviously. Improbable? Also yes. Impossible? No.
That's an uncharitable take that focuses on the wrong issue, in my opinion.
Noland's life was pretty dire: "Since dislocating his C4-5 vertebrae in a 2016 swimming accident, Arbaugh had dropped out of Texas A&M and returned to live with his family in Yuma, Arizona. Due to the combination of Yuma’s scorching heat — from May to September the average high temperature is 99 degrees or more — and the intense spasms he experienced when sitting in his power chair, Arbaugh spent most of his time in bed, watching TV. With no sensation or function below his shoulders and having limited caregiving hours provided by the state, he relied heavily on his parents and brother and often felt like a burden." [1]
After Neuralink, the abilities that Noland gained is best represented by his own words: “Before, I would wake up and just [watch] my TV,” he says. “Now, I wake up and [work] on my computer. It’s very similar, but at the same time, my daily routine has changed from just watching stuff to being more active and interactive with the world.”
