It makes sense if your employer views your position as commodity, like a warehouse worker. "Here is your labor area we carved out for you to do your commoditized work units, one size fits all". The same reason JIRA is popular with management. Gives them visibility and "metrics" to improve. A less-charitable interpretation of hot-desking is that it's a constant reminder that your job is not secure, and that new people can come and replace you instantly, vs your own personal place in a cubicle or private office signals some amount of commitment that you have "your spot" at the company.
