Semantics. If the hobby business never makes a profit and is capturing losses for tax benefits, that’s a failing business. It can be failing indefinitely as long as there’s money to support it, but you can’t call it a successful business.
You appear to be suggesting that fun hobbies which don't make money are a 'failure' rather than a success. Not everything is judged by how much money it makes.
Have you ever wondered why kids climb trees?
Doesn't running consistent losses eventually cause tax issues with the IRS? If the losses are offsetting profit elsewhere, I would assume the IRS would become very interested in challenging the validity of the hobby business?
