All true. The reason there isn't a publicly available download link for anything above Service Pack 2 is because SQL Server 2016 is already past mainstream support and isn't sold anymore. SQL Server 2019 is the new kid on the block. So, no, you will not get SP3 as a download via the public list.
I subscribe to Visual Studio just for these occasions and for many other reasons - the primary being I'm a developer along with being an IT Professional.
