Does "James was caused to become drunk at the party" mean "James, because of someone or something, was drunk at the party"?

Does "Elsie got her hair cut today" mean "Elsie, because of someone or something, cut her hair (=> Elsie went to the beauty salon because not she wanted to cut her hair, because but her father forced her to cut her hair)" ?

Does "We get our clothes washed at the laundry" mean "We, because of someone or something, washed our clothes at the laundry (=> We washed our clothes because not we wanted to wash our clothes, because but our mother forced us to wash our clothes)" ?

Answer 1

"Get", besides "acquire", can mean "become".

James got drunk at the party.

In the above example, James became drunk at the party. He probably drank a lot of alcohol. It could have been by himself or someone else made him drink a lot. He just became drunk.

Elsie got her hair cut today and she looks lovely.
We get our clothes washed at the laundry.

In both those sentence, "get" doesn't mean "to acquire" or "to become". Instead, this is a common verb phrase:

"to get + something + V3 (passive)".

In Elsie's case, the Subject (Elsie) did something (went to the salon; let a friend cut it; cut her hair herself; etc) that resulted in her hair "being cut", which is Passive.
