The decentralized nature does mean that sometimes criminals can use it, but some countries will consider you a criminal based on the color of your skin.

There are already cryptocurrencies with barely a fraction of the energy use of Bitcoin.

Like my Excel spreadsheet!

Well, yeah.
A blockchain is nothing more really than a database.
The use case is when I don’t want or have a trusted keeper of that data.
See, if it’s your excel spreadsheet, how do I know that you’re not going to change the values on it? For some things that doesn’t matter - but for things like funds between different parties, etc, that can be a big issue.
Traditionally this has worked by having a trusted third party - a bank, a court, a escrow company, etc. But all these require lots of effort to have as well, and can be bad actors.

Don’t get me started on all the other issues Bitcoin has…
