Does this $4.3 Million photograph obstruct other photographers

This is Rhein II Photograph ,a photograph taken by Andreas Gursky, sold for $4.3 million. It’s considered one of the most expensive photographs ever.

Elsewhere in this sub I’m seeing claims how “Hoarding Wealth” is bad for economy, as discussed here: Debunking the billionaire hoarding myth in a single meme

Would someone explain please how this Valuable Thing in the hands of a single owner prevents or obstructs the existence of people having other Valuable Things?
