Reservoir on the ocean floor safe way of storing liquefied CO2 for a long time?

The piece is about hiding CO2 as liquid on the deep ocean floor.
Personally I'm more in favor of removing CO2 the way that it happens naturally: by erosion and weathering.
CO2 gets chemically bound into some kinds of rocks. Enhanced weathering involves crushing olivine or similar rocks, and exposing the powder to air for a few weeks in a hot place, and then dumping it in the deep ocean.
It's what happens naturally. It'd just be quicker with mechanical assistance.
The thing I can't get is that that public interest in things that are unproven and/or unscalable (like carbfix requiring a few tons of water to dispose of a ton of CO2 or the idea of spreading olvine on the beach where you have no idea if it accomplishes anything) get so much attention but there is little enthusiasm or traction for saline aquifer disposal which the literature says is good to go.
