Reason why you should always look at the big picture. Your arguments have their merits and no one said bidbots are gonna die or peeps will stop self-voting. No.
The original point of this argument was to have a system where there will be very little difference between self-voting / delegating to bidbots and voting on other people's works.
50/50 does that. If the profit resides with bidbots, stakeholders will delegate to them. But if the profit resides with both bidbots and normal posts, stakeholders will at least think twice about what brings more value to Steem in the long term!
50/50 doesn't get to the point where there is little difference between self voting and curating. Self voting still gets 100% while curating only gets 50%. But it narrows the gap a lot from the current 100% vs. 25%. The idea is that along with other changes (especially cheaper downvotes) this is enough to achieve a balance.
