As per your example, the perfumes were so expensive that a certain person wouldn't be able to afford them. So how can such a person who lives hand to mouth, will be able to invest in bitcoin or gold in order to have financial freedom? He can't unless he does not have ways to earn more money.
It's very difficult for someone who doesn't have wealth as an inheritance to make enough money that they can use for investments that can give them and their family and children a financially safe future. For those who are lucky, their parents or grandparents must have made their empires and now they will inherit that and enjoy the life and the luxuries of it, but those who are deprived of that will have to struggle in their life to earn a bright future.
So, it is only that rich people can invest more and hence they will get better financial freedom. A normal person first may not have the capital to invest and even if he saves some money for investments, the return on small investment may not be that high that it can give financial freedom to him.
Well, for someone who doesn't earn a lot of money, it's difficult to have savings that they can use for investments, because they will have to keep some money that they can use if there is an emergency because it's life, and anything can happen at any given time, and if you don't have any money when you face an emergency, it becomes a problem as you will have to ask your friends, family members, and relatives to lend you some money for the situation.
