In your post you keep stating, ' You have done this, ' and until ' You do this'.... You are only talking to eBay members here, just like yourself, buyers and sellers, not eBay themselves , they do not come to these forums, (more's the pity 🙄 ).
Simple Delivery is mandatory for Private sellers, and here to stay.
Yes, it's not liked by many, there have been mile long threads from disgruntled members, and I'm no flag waver, it's not faultless by any means, BUT, it does have some big pluses.
An item sent by Simple Delivery, if lost in the post or arrives damaged in transit to the buyer, then eBay pick up that refund, they refund the buyer, and the seller gets to keep the payout.
That can't be bad.
As said, many things need to be ironed out, changed, corrected, was it introduced a tad too early ? 🤔
In my humble opinion..... Yes.
