The 20 million could have been used to help many more people than a single family though.

In this case specifically it's unlikely the family sold an asset simply to buy another asset. They've had it a few hundred years, and the gallery has had their eye on it for decades. It's likely they sold it cause they needed the cash, for a new roof or whatever.
If they spend it, then those people providing the goods and services will prosper. If they invest it in a business, then that business has capital to grow, and all those employees will benefit.
How does that work (I'm not in the the UK)? Donations perhaps?
