Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.

This line summarizes the crux of the story. Instead of calling for making devices cheap (easiest way will be government funded manufacturing), so called healers are calling to ban/regulate use of used devices.
If somebody will look in to the background of opponents of use of second hand devices, most likely they will find affiliation with big manufacturers. Used device use will certainly bring the cost down and so will be the profits of the companies.
As long as safety (infection) can be proven, potential benefit outweighs the risks (failure of device).
