Are you a mental case!?
The Grateful Dead allowed their music to be freely traded. I have a large collection of their bootlegs, and no, that doesn’t make me a thief.
Please take your meds.
Not every group has a coterie of insanely rabid fans to follow every thing they do and buy out their every one of their concerts. Groups like that are rare and far between. Some performers cannot even do live performances. Others the cost of performing far exceeds the income possible to be brought in. Recording sales provides their income.
