If that ends up happening, then the next step would be for the platform to derank listings that contain AI-enhanced photos, to set the proper incentive. That would be up to the platform to enforce, though.
What incentive does the platform have to do this? Ostensibly, the agents/landlords are the ones who pay, so you're asking the platform to bite the hands that feed it.
It's not "if." My mother-in-law is a realtor. She has a storage locker full of furniture for staging. I guarantee that the monthly cost of that locker, plus the cost of moving the furniture in and out of every property is an order of magnitude more expensive than whatever tool is doing the AI fake staging. The cost savings are too attractive.
