To my knowledge, in small volumes vinyl is cheaper to produce than CDs. So, if you want to get a physical medium, it might be the only choice.
I saw a documentary a while back about a region where new local songs were pressed into records on a weekly basis, I think it was in Jamaica. The local music scene was highly ephemeral, and people's records were constantly being recycled for this week's new tunes.
Digital files are even cheaper.
I doubt vinyl is cheaper at any scale. At least in the UK, 250 packaged CDs are 60% of the cost of 250 unpacked vinyls.
