I abbreviate 'Counterfactual Conditional Statements' to CCS and 'Material Conditional Statements' to MCS.

Subjunctive conditionals are often called counterfactual conditionals because their
antecedents are typically false.
1. Why does the quote above emphasise the falsity of CCS's Antecedents? MCS can also have false antecedents; so what? What differs? For example:
2. If E is a rare element, then E is costly.
3. If E were a rare element, then E would be costly.
Most physical objects are NOT rare elements; so both 2's and 3's antecedents are false.
