Indirectly common people are being seized from their humanity. I guess the disliking people know how immigration is not something freely accessible, lots of people around the world just don't have the necessary conditions to leave the country where they were born against their own consent, be it Russia or whatever other country.

I'm sure lots of Russians were already angry with their government way before the sanctions, so what now? Ideally, people could do massive protests, Putin would be scared as heck so he renounces, people invoke the good old democracy again, they vote, a new leader takes place, Ukraine-Russia war would cease, both Russians and Ukrainians would happily fly together mounted in winged unicorns... Except everyone knows it doesn't work that way!! Governments (not just Putin's) have multiple ways to fight any protests going inside their country, governments can tear gas citizens, governments can end lives from their own citizens, governments can end a protest before it even happens through censorship and massive electrical/internet blackouts. Even when citizens has guns, governments have stronger guns. Lots of recent examples are there to demonstrate how this happens.

People from a sanctioned people can and will starve and die, because their governments and their bureaucrats and forces (police and army) can have their own sustenance, so it doesn't really matter for them if their own citizens starve to death. Russia, China, Cuba, Venezuela, North Korea, they won't change simply because population became angry: I guess everyone in the west remember the Tiananmen Square, did it change China's government? I guess no.

So instead of sanctioning and indirectly punishing the people, one option would be that organizations (maybe Red Cross, UN, I dunno) could intervene silently and peacefully inside a country, helping people to flee their country to a safer place, effectively reducing that country army's recruitment potential and weakening its military power (did anybody from NATO, WEF, UN, or whatever organizations, even thought about this, helping Russians flee away from Russia in order to weaken Russia's military?).

It's worth remembering that military recruitment is often a mandatory thing, and the only way common people can run away from it is running away from the country, something that won't happen if they have no money to start emigration processes (it costs money, you know, it's not a free thing, even seeking political asylum needs money). Cutting money will only cut lives unrelated to the leaders that are carrying wars (and I'm sure Putin won't cry because Ms. Mary Marylovski died from starvation because US and Europe indirectly cut her income, because Ms. Mary Marylovski is another unknown citizen to Putin or other higher level government bureaucrats).

I digressed from technology here, but those are my thoughts on the matter.
