Nor do I like IP space being an overallocated and hoarded asset.
I feel like grandparent poster probably doesn't know the upsides of IPv6.
I do actually remember following its development, hate NAT, and of course feel constrained by the V4 32-bit address space. But V6 has its designs problems too and while over the years I’ve tried to use it, it has never been worth the hassle and, yes, is slower (probably because most connections are to V4-only sites).
Ok.
But I do think my joke wasn't very good, in retrospect so your comment is not surprising.
