Rights to impose your will about something, should end at the point where you sell this thing to someone else. That's how it should be. Sadly a lot of companies are trying to rent rather than sell (see: ebooks, anything as a service, etc.) because this way they don't lose control.

What if a buyer wants to lease the product under the seller’s terms. Should it not be their right to enter that agreement?

That's called renting, not buying. There's no buyer in that case. And that's exactly the rent-seeking trend I talk about. Most virtual "purchases" are actually just rent because you don't actually own the thing.
