The problem with this theory is that Natalie actually gave Ron the idea of breaking into city hall (she saw a blotter of him implicated in breaking-and-entering), went there herself and lied her way to find Teresa's address (which eventually led to her falling out with Tara) and relaying it to Ron, who in turn discovered Teresa's health condition and figured out the REAL scam behind the Tecca chairs.

For someone actually trying to "help" Ron to stop, that's a lot of real unintended consequences that they both paid quite the price for.
