The impact of the death of ToysRUs will be significant to the toy industry as a whole, as Walmart/Target only devote a couple of hundred linear feet to toys, and Amazon has killed the little shops that powered the long tail.
"The departure of Toys 'R' Us from the retail landscape will give a boost to neighborhood toy shops.
That’s according to the American Specialty Toy Retailing Association, which predicted that 2018 will be the best year yet for neighborhood toy stores nationwide as consumers flock to these stores in the wake of the closure of Toys 'R' Us."

To the extent that vendors were relying on being propped up by an unprofitable Toys R Us who bought their product for more than it was worth, it's the same effect one level up: those vendors were consuming more value than they produced.
An unprofitable company is an overall loss by definition - sure it's providing some value to some people, but it's consuming more value than it produces.
Killing the company quickly frees up the things it was consuming to be used for more productive things. Those buildings can be used for better businesses, or replaced with housing or parks or what-have-you. Other companies can offer better jobs to those workers (we're at close to full employment at the moment, and declining companies are not fun or fulfilling places to work). Money that was invested in that company can be put to more productive work in other businesses.
