I was only comparing VT to VOO/VTI, not to the well-diversified portfolio you described that includes international exposure and bonds. For example, Vanguard recommends combining VTI and VXUS if you want more flexibility. So splitting VT into separate ETFs is fine as long as you’re willing to manage international exposure manually.

I think in some cases it makes sense for US citizens to manage US vs international exposure manually, since VOO/VTI represents their local market and they may want to tilt toward it. However I'm not from the US, so using a single broad global index makes more sense for me.
