Using a reputable VPN who claims no logs still places immense trust in that VPN provider. If you're a journalist or political dissident, it's possible your life is resting on that trust.
Alternatively, You -> ISP -> Tor -> VPN and paying with Monero obtained over Tor without ever having disclosed your ID or any revealing info means:
• Your ISP knows who you are, but not what you're doing (no anonymity, yes privacy). The connection to tor establishes privacy from ISP.
• Your Tor exit node sees you're connecting to a VPN, but does not know who you are, or what you're doing (yes anonymity, yes privacy). The routing of Tor establishes anonymity, but not privacy from the exit node. The connection to the VPN establishes privacy from the exit node.
• Your VPN provider knows a bit about what you're doing, but not who you are (yes anonymity, less privacy)
This offers additional protection if your VPN provider is compromised / lying about logging (you have no way to verify at any given moment, only that they weren't in past incidents that have gone to court, but this is no guarantee they can't be compelled to start logging your connections).
This also offers additional protection if your guard node and exit node are compromised, which is sufficient to deanonymize tor users.
What it does not offer protection against is all ISP's involved selling netflow metadata to a single party who uses timing and packet sizes to correlate traffic across all of these connections, like Team Cymru does with their Pure Signal Recon product (formerly called Augury).
If that scares you, I'd encourage you to look up what company actually owns and operates torproject's website, and how many contracts they have with governments, too.
