I think that this approach makes the most sense, as it becomes a tool to distribute SP to the minnows. As you might already be aware, it can be difficult to build SP from nothing.
Thanks to various initiatives like Steemsports posts and your poker stake posts, it's now possible for newcomers to have equal footing with the high-SP holders to gain SP. I think it's important that this platform has at least a couple of these options available to the community - it just seems fairer to me.
If high SP-holders want to increase their SP value, they can always look to curating - something that minnows are basically ruled out of having as an option to grow wealth.
Thank you for your feedback! :)
