the only way of having backing properties is doing something like this?

class C {
    private val _elementList = mutableListOf<Element>()

    val elementList: List<Element>
         get() = _elementList
}

It depends if you want to cast MutableList to List, but you can also:
1. Create a method

fun elements(): List<Double> = elements.toList()

2. If you don't want to change into immutable list, then

var elements = mutableListOf<Double>()
        private set

3. Or if you want to have it visible, then simply:

val elements = mutableListOf<Double>()
