To me, proof-of-stakes means that results are achieved with money. It isn't necessarily bad. But it is a different proof. Let's look at visibility and marketing for example. Paying people to talk about you is proof-of-stakes marketing. It proves you were willing to put capital forward to be seen. It could prove that you believe in your product. It means you are putting stakes on it. Proof-of-Work marketing isn't achieved with money. You work and show this work everyday. People see the proof that you work everyday. They start to trust you. Others talk about you. They buy your product and start recommending it. This can't be bought. It's earned over time. Maybe this isn't quite the perfect example but I hope you can see where I'm coming from with this. This concepts applies to almost everything. Take a store for example. A store use money to acquire products and resell them at profit. I would say such store is *mostly* proof-of-stakes. What was most needed was capital to rent the building and buy products to sell. The more capital your venture requires, the more proof-of-stakes it can be considered. Something like painting requires almost zero capital. It is pure Proof-of-Work. And that's when we start to talk about Art.
