I consider streaming services like a library. Tidal (as well as spotify etc) allows me to explore in depth particular artists, composers, conductors, genres and so forth. It is simply not cost effective to do the same by buying CDs, vinyl or books (in the case of a library).
In addition, I've enabled Tidal via Roon, and I let Roon make recommendations via Roon Radio - discovered tons of stuff I would never have simply by buying CDs.
But of course a downside with streaming services is that it requires an internet connection.
