My view as well.
Changing the deductibility is plain dumb IMO - it is a business in the simple meaning of the word. Generating an income and therefore expenses incurred in generating that income should be a deductible expense. Get their tax if sold within 10 years.
Yes I know does not produce anything, but still income generating and providing a service, must be other businesses out there that do not produce anything - e.g. widgets but provide a service of some description, they would still claim interest if applicable...
