It depends on what the "meaningful change" actually is. Lots of possible changes are meaningful but not worth killing people over. Not all proposed changes are actually possible. Mobs of people are usually really stupid and bloodthirsty. Look at the 1970 Cambodian coup for example. You don't want to open that Pandora's box unless there is a real urgent emergency or violation of natural rights. If people were as excited about losing weight as they are about some CEO getting shot, we could all have much cheaper insurance and maybe the government could even afford to give us free health care. You should look into what the government pays for and how much they pay for it. It's really eye-opening. The government isn't a magic money machine. If they pay for something, the value is extracted from somewhere in society either in monetary form or through inflation.
