Feel free to complain about "tax loss" as in the government getting less money than they would otherwise, but it's definitely not a "tax dodge" - tax dodging only makes sense if you actually end up with more money than you would otherwise - i.e. you "earn" $100m but then you "dodge tax" to pay only $10m tax instead of $20m, and end up with $90m after-tax income rather than $80m. Multiple ways of doing that - the obvious one is moving your tax residence to a 0% tax haven, the less obvious one is to artificially inflate the value of an asset (e.g. a work of art) and then "donate it" and write off that from tax (e.g. buy it for $10k, donate it when it's "worth" $10m, write that off as a "loss" and pay only $10m tax instead of $20m).
