Why are you comparing yourself to the Prophet saw? Your points are mute because the prophet wouldn’t go against the word of Allah.The prophet gave all his money away and there are many stories about his family not having enough post khadijah on numerous occasions. Plus he left all his wealth behind in makkah or whatever was left of it. The boycott bankrupted the Muslims of makkah and when they made hijab they basically all left with nothing but there families. The comparison is there so you understand
The rules of polygamy are strict in Islam. The means of providing for a family are much different and much more expensive in the present day.
