Indulgences can’t get us back in the Garden of Eden. So not all temporal punishment can and will be remitted by indulgences. This is why I believe it is impossible for me to get a plenary indulgence. If I manage to make it through this life, I’m going to be in purgatory and will be turning off the lights at the end.

All temporal punishment can be eliminated with a plenary indulgence. What is removed is an unhealthy attachment to creatures, and this requires perfect contrition.
Some of what you speak of is not temporal punishment for sin – only temporal punishment for sin is removed by indulgences.
Consequence of the original sin for humans
- Adam and Eve lost supernatural gift of sanctifying grace
- Adam and Eve lost preternatural gift of immortality
- Adam and Eve were expelled (to not eat of the tree of life) and would have new difficulties
- no gift of sanctifying grace at conception for mankind (the stain or original sin)
- no gift of preternatural gifts at conception for mankind
For actual sins (mankind including Adam and Eve)
- eternal punishment (for unforgiven mortal or serious sin)
- temporal punishment (for all sin) *
- other consequences that we have to endure in our life as a result of actual sin
- the need for penance (satisfaction for sin) **
- removable through purgatory or indulgences or baptism or sacrament of confession.
** Absolution takes away sin, but it does not remedy all the disorders sin has caused.62 Raised up from sin, the sinner must still recover his full spiritual health by doing something more to make amends for the sin: he must “make satisfaction for” or “expiate” his sins. This satisfaction is also called “penance.” – Catechism 1457
The Garden of Eden was not perfect. There was the tree of knowledge of good and evil there and even after the first sin they remained in the Garden of Eden with fear and ashamed of nakedness, before their expulsion.
So although mankind does not have the preternatural gift or gifts that Adam and Eve had God has made if possible to receive eternal life, after living our lives with the suffering inherent in earthly life, and uniting that suffering with that of Christ, as St. Paul wrote:
Colossians 1:24-26
24 Now I rejoice in my sufferings for your sake, and in my flesh I am filling up what is lacking[a] in the afflictions of Christ on behalf of his body, which is the church, of which I am a minister in accordance with God’s stewardship given to me to bring to completion for you the word of God, 26 the mystery hidden from ages and from generations past. …
1:24 What is lacking: although variously interpreted, this phrase does not imply that Christ’s atoning death on the cross was defective. It may refer to the apocalyptic concept of a quota of “messianic woes” to be endured before the end comes; cf. Mk 13:8, 19–20, 24 and the note on Mt 23:29–32. Others suggest that Paul’s mystical unity with Christ allowed him to call his own sufferings the afflictions of Christ.
