Recently, some people have been comparing LST/re-staking with RWA and even the yields from U.S. bonds.

I find it a bit uncomfortable to watch...
To be honest, most of these "extra" on-chain earnings are not just falling from the sky;
they are usually earned by taking on more risk: validator rewards, protocol subsidies, and others willing to pay for security.
Layer upon layer, it sounds appealing, but any problem in the middle could cause a chain reaction.
Re-staking is especially like selling the same security multiple times; is demand really that stable? I don't know.
Anyway, I’m currently testing with a small position, mainly watching contract permissions, redemption queues, and what happens if I get penalized or confiscated—who will cover the losses...
I still believe this approach can work a little, but don’t treat it too much like a "government bond."
That’s all for now.
