People often mistake having more money with being more wealthy. Governments can print money and it does not help them. Money is a way to exchange value. It is not value on its own. You can have unlimited bank account, but it will not help you if there is nothing for you to buy.
Wealth of people, companies and countries is increased only by producing more value. Products, services. You can become rich by buying bitcoin or index funds, but you might not be wealthy.
Will you be able to buy something with the money when you will need it? Will someone be willing to buy the stuff you own when you will need money to buy something else? And for more than it costed you?
Being wealthy means having various assets that you can exchange for other assets valuable to you when you need them. Having all eggs in one basket does not create this for you.
