This sounds like a very naive point of view, you might as well say "don't breath".

The entertainment industry EMPLOYS people in such a wide variety of direct and indirect roles. People involved in creating the entertainment, translating the entertainment, marketing the entertainment, manufacturing and distributing the entertainment. Every aspect of creating an entertainment product (music, games, movies, theatre and more) employs people directly, and all of those direct employees spend their income in indirect ways that benefit you, for example spending in local businesses, paying their mortgages (which underpin pensions and economic stability), transport services (like busses, taxis etc), their family (days out, on kids etc), in their community, investing and also... on TAXES of all shapes and sizes.

You might have the opinion of "F the world", but unless you're living under a rock you directly benefit from all of the industries that are part of a functioning (local or global) economy.
