The wealth tax is major reason for me to have left Argentina this year.
The advice of the lawyer I visited was: try to avoid triggering becoming an Argentine resident. To be safe with migraciones, you could not stay more than 180 days per year in Argentina. The Argentine taxes have another criterium, for them you need to have spent less than 90 days per year out of Argentina, this is less strict. (Once you are a resident it is harder to get rid of this status). The biggest issue is migraciones, if you overstay without being a resident, you risk being denied entry to Argentina after you go abroad.
Another option is to hide your wealth. I think the US and Argentina so far do not exchange information about people's assets, but most European countries do to some extent. You have to decide for yourself if this is what you want to do.
Another option tax-wise is Uruguay. Uruguay only taxes what you earn inside Uruguay and does not care about your assets abroad. It is not the same country though, but it is close to Argentina, so Argentina is easy to visit.
