It's $0 to go to Bittorrent and download movies, it's $0 to use adblocker and not have Youtube premium. There will almost always be piracy or piracy-adjacent cheaper options.
Arguably you want to spend a bit more than $0, e.g. a good VPN or a good seedbox. And VPNs can be as expensive as YouTube premium. (That said, VPNs have other uses, but "most people" probably don't really use VPNs much anyway)
Usenet costs around $3/m if you find one on promo. You don't need a VPN for that as it's all encrypted. YouTube Premium family plan costs $22.99+tax per month in the US. While it's not free, it's very close.
