I'd have to disagree with it being an immersion breaker. The period's diplomacy involved a range of diplomatic mechanisms, often without resort to warfare. Territories routinely changed hands for money, or even in exchanges for other territories.
I really think we need some way to negotiate with other nations other than declaring war on them. If we want to stop human players exploiting the land purchase system, then just make it prohibitively expensive to engage in.
AI countries should be really reluctant to part with territories, and rightly so - you should have to pay through the nose for the privilege.
But TBH, I can't really think of a situation in Vicky 1 when a human player could really exploit the land purchase system (with the possible exception of uncivs using it to declare war on other uncivs they didn't share a border with, and that loophole was tightened up). Even in Vicky 1, a province cost a fortune.
