If the AMC in the SIA is as high as 1.25%. It’s clear cut. Contribute up to €50k. Remove everything above. That’s a 38% tax rate (assuming average 6% return in your example) with equivalent to annual deemed disposal. God awful not worth considering.6% return
1.25% AMC
Practically, I will be very surprised if you are not able to access the same ETFs (VALL and WEBN are 0.07-0.12% TER) through the SIA with Zero direct fees from IBKR, Revolut and T212
