The question is opinion based as nobody can give you realistic forecast to what will happen to the world economy under some completely unrealistic scenario.
Question that cannot be answered with some published research/work/textbook as a reference or with reference to real world data, will necessarily require people to state opinions.
In addition, people can choose only one reason for closing question, but your question could be also closed as:
too broad: on this site we do not allow questions that are too broad. Questions should be narrow about some specific problem.
needs details and clarity: scenario in your question is extremely vague. What even counts as almost unlimited amount of money? what time frame we are even talking about? etc
Chatty questions, that can't be answered by facts and research, questions are too broad or vague are considered off topic on this site. See more details in our help center.
