No one have the right to abuse someone financially. We just need to make them aware or to educate them. It's their own choice whether they adopt it or not. The only thing we can do is that as human beings, it is our duty to tell him that Bitcoin is a great investment asset, and we can earn profit from it by just holding it. The rest depends on people whether they believe it or not, like Bitcoin, they willingly adopt it or decline it.
In fact, such people do not have any dedication to how rare is Bitcoin. If they knew, they would have gone ahead of us and grabbed Bitcoin, but alas, these poor people do not know anything. We should leave such people to their condition because these people do not want to change their condition. It is better to focus on your investment plan rather than explaining it to them.
Promoting financial education is important, but it's just as important to acknowledge and respect diverse viewpoints and investment approaches. Instead of dismissing them, it could be a better approach if we foster open discussions with them. It is not a matter of forcing someone but it will help to adopt with financial freedom.
