Is it stupid to invest in these stocks as a non-US resident ?

VOO/SCHD/VT/VNQ/VNQI

I want to invest for the long term. I was planning on putting around 75% on VOO and diversify the rest among the other stocks. However, after realizing that I’m subject to 30% dividend tax (country has no treaty with the US) I’m not sure it’s worth it to spend a dime on high dividend stocks anymore even just for diversification.

Im a complete beginner to this obviously.

Any advice ?
