It’s only expensive because it happens so episodically that it doesn’t require automation. Automation leads to scale leads to reduction in cost. The analysis humans do on top of it can be done through a periodic filing, but the totality of disclosures can be done continuously other than the periodic human opinion fluff. The notes and details can be filed as they are relevant without undue burden. (I.e., a large onetime expense can be explained as it happens - I assure you it is being explained internally at that time in more detail).

I was at a large Wall Street firm which closed its books daily and has done for decades. They disclose daily to the fed and others. It was work for sure but the benefits of constantly knowing your business far out weighed the cost. So I don’t buy that it turns into more theater, you can’t do theater at a continuous pace. Theatre takes time, and the level of theatre increases as the pace of disclosure decreases.
