Somehow we should think about saving for the time of emergency so that we have to get something when we immediately needed some funds. We can't be so sure when an emergency situation happen so its better to separate some funds for security. Although its really good to invest but the problem there if we can't take out our money when the time we need it the most. For sure we will be in a lot of trouble and for sure to get a lot of stress since we think about we have money but we already put it on some things that we think that can generate us a profit in future but we can't take it anytime we want.
What do you mean by we can't take it any time we want? Aside ponzi, is there any other investment that you will not be able to take your money when needed? I don't think so. One thing with investment of this type is you might be swimming in a lose if you want to take your money at the wrong time. When you hear invest what you can afford to lose, this is the situation they are talking about. You don't invest with the money you might need for emergency no matter how profitable the investment sounds unless you're ready for the risk ahead.
Apart from that, saving always has problems with inflation. So, the value of your savings could decrease without reducing the amount. However, with investment, we can generate additional income at any time.
However, I also think that it would be better to prioritize investments because they can be a very good thing when we have entered old age, or perhaps retired. The investments we make today can be a new source of income, and in fact, in many cases, people who focus on investments have much more income from investments than from their main job. However, investing is a very good thing, but we also need to save because we don't want to sell the investments we have when we need money in an emergency. at that time, savings are very necessary.
Reading from OP I see how everyone is speaking about the cons of savings. With no doubt, the value of your savings could decrease without reducing the actual amount saved but are you also aware that in investment, the value of your investment can also decrease drastically without reducing the actual size of the investment? I see both investment and saving as two different entities meant for separate purposes. Everyone can save but not all can invest, it depends on your goals and plans for achieving them.
