Those payment instruments are generally subject to fairly low transaction limits due to the potential for abuse. Cash is the exception there, but it's extremely inconvenient to move or store large sums of cash and nearly impossible to do so anonymously.

Ransomware gangs do not choose to accept cryptocurrency payments because it aligns with their politics; they do so because it is the only way to move millions of dollars across international borders in an undoable fashion.
