The result of that is not earning a curation reward and the cost is losing that voting power.

That's true only if one makes very bad votes 40 times everyday. If they do not make such a mistake, there are some profit.

Let's not continue to make arguments based on the skewed results we see today due to disproportionate pre-mined stakes and imbalanced incentive structures.

Many for-profit bots are from non-pre-mined accounts. Curation reward is a separate issue; not heavily related to fairness but related to wrongly designed incentive system.
