Maybe for an expensive piece of business equipment. For a consumer device I don't see that working -- the logistics of the "inspection" would impose prohibitive costs and administrative hassle. If someone doesn't submit to inspection you just turn them off? Seems like you want a subscription model based on usage, not a pay-for-use setup for the hardware.
It's not a subscription model but rather a user feedback loop. Basically the producer should prove the device is still working rather than the user proving it's not working.
