How would have the world changed and how would it look like today if barter were the only way of payment up to this day?
I believe you meant to ask: How would the world have changed and what would it look like today if bartering were the only way of making payments to the present day.

If bartering were the only way of making payments today, the world would look drastically different. Transactions would have to be negotiated between two people, and the value of goods and services would be determined by the parties involved. Money would not exist, and so there would be no central banking system or standardized currency. This would make it difficult to accurately and fairly measure the value of goods and services.

In addition, the limitations of bartering would mean that long-distance trade would be almost impossible. Without a standardized system of value, it would be difficult to agree on a fair exchange of goods or services. This would limit the ability of people to trade and exchange goods and services with people from other countries.

Bartering would also limit the growth of businesses. Without money, businesses would have to rely on bartering for their goods and services. This would make it difficult for businesses to expand or invest in new projects, as they would have to rely on bartering for their resources.

Finally, without money, the unequal power dynamics between different classes could become even more entrenched. Without a standardized system of payment, those with greater resources would have access to more goods and services than those with less. This would likely lead to a greater divide between the rich and the poor.
so you would be growing your food to be stolen by the next biggest guy on your block.
