One aspect that wouldn't eliminate the issue of "useless" or fake tx would be to have the liquidity aspect be a modifier where stakes being il-liquid devalue but over some threshold, the stake modifier is at a constant 1x. Another potential mitigation tool would be to have the protocol look for tight tx loops (i.e. Naive liquidity falsifying) and either negate or reduce their influence on the liquidity calculation. Whether this is actually possible I have absolutely no idea. If I was to have any real trust in this idea I would have to look for/develop either formal proofs or some real demonstrable examples of it working. Beyond that I think it boils down to game theory and economics. If it could work, it would likely require careful calibration to minimise the benefit of gaming the system or otherwise being a bad actor.
