I would say they already have, it being the entire point of the Cold War and several times thereafter. The current sanctions are certainly economic interference designed to change Russian politics, too.Your response to that specific paragraph, implies that Putin considers The WEST/EU/NATO, "expect, to interfere with the internal economies, politics, societies, and defence" of/within, Russia ?!
We also make a lot of noise out of interfering in the internal economies, politics, societies and defence of other nations on a great many occasions on the basis that we believe it the right thing to do, so why not Russia too?
That's the trouble with mistaking power for virtue and 'can' for 'should' - other people can do it too.
