Great question! For me, it's the "be your own bank" aspect. This sounds like a simple phrase, like a kid clutching a piggy bank with both hands. It's not that. At all. It is far deeper.

I am running a full Bitcoin core node and I stream every single on chain transaction in real time getting validated on my computer and then I share block confirmations with...Let's see:

$ bitcoin-cli -netinfo
Bitcoin Core client v26.0.0 - server 70016/Satoshi:26.0.0/

         ipv4    ipv6   total   block
in         54       0      54
out        10       0      10       2
total      64       0      64

Local addresses: n/a 

64 other Bitcoin nodes and we all agree that our accounting checks out. And those 64 connect with all the others to form an impenetrable ring of certainty. This takes the concept of double ledger accounting to the quantum level.

Also, incredibly, I have the entire history from the genesis block to block 834458 that I just validated that I can view and analyze in its entirety. I can create wallets at will and fund them. I truly am a bank. My bank. And your bank. We collectively form the bank, and my contribution is absolutely every bit as crucial as any one else's, along with the miners, to strengthen the network. It is truly empowering.
