There is a reason for hoarding data: it’s an asset on the balance sheet. So long as it is legal to liquidate data for cash, there will be incentives to collect and keep it.

That is the point. Make it illegal, and not something that can be handwaved away by an EULA or TOS.
Or at least make it a liability on the balance sheet rather than an asset. Sure, you can store as much user data as you want. Oh, what's that, if it leaks you owe each user $10,000 under the new law?
