You are looking at from the words as it is written. I am applying the spirit behind the purpose of tithing and to be honest it go way deeper than giving money or possessions which ever way you prefer. I am looking it from a wholelistic approach.
The word is "holistic" and it has nothing to do with tithing. Tithing is purely an old covenant requirement; nothing more. Conflating "tithing" with "giving" only causes confusion and results in Christians trying to be acceptable to God by following bits of the Law, or to earn His blessing by giving as their pastors (mis)teach them.
We all know in those days, they didn't work with monetary notes and coins. The worshippers brought of their crops and etc.
If you're claiming that they didn't use money in those days, you're incorrect. There are many references in the Torah to money, such as the following:
Deuteronomy 14:24-26 But if that place is too distant and you have been blessed by the Lord your God and cannot carry your tithe (because the place where the Lord will choose to put his Name is so far away), then
exchange your tithe for silver, and take the silver with you and go to the place the Lord your God will choose. Use the silver to buy whatever you like: cattle, sheep, wine or other fermented drink, or anything you wish. Then you and your household shall eat there in the presence of the Lord your God and rejoice.
What was purpose of worshippers bring their tithe or first fruits to the storehouse?
To supply food for the Levites and priests whose job was to minister, judge, and teach.
