Yep! But there should hopefully be an efficient + cost-effective incentive for others to host your content when they implement FileCoin.
Or you could just host it on your own devices, so long as you're okay with it only being reliably accessible so long as at least one device is up and running.
The difference with regular torrent seeders is that they have no incentive to seed once they have the content. In this case the main purpose and goal is to "seed" and provide content to others, so the long tail should be more resilient.
