1.
They are 1 on 1 mapping. Cannot see why you trash one but value the other. All demand-supply questions can also be solved using total utility but marginal utility is much easier.
2. Limit and 闭区间/开区间 are different concepts. Interval with no limit is open interval but interval with limits can also be open.
3.
In economics, there is literature investigating limited/bounded rationality and information economics studying asymmetric and/or incomplete information.
4.
Incorrect, you confuse supply in equilibrium with supply curve. BTW, nonlinearity and discontinuity are well studied in economics.But keep in mind that all models are approximation. A more accurate discontinuous curve may generate more problems than solve any.
5.
There are many employed, maybe too many. An overly complicated model doesn't guarantee accuracy, usually it leads to the opposite.
You understanding of supply-demand model is very wrong. You will fail the introductory course of micro economics US college students usually take in their 2nd year. Grab a textbook and read. You don't seem to know what you're talking about.
Your concerns about rationality and continuity are, however, reasonable but not original at all. You can find many papers via google scholar.
