Old-fashioned bad openings

I see sooo many old openings like:

• King's Gambit
• Ruy Lopez: Berlin Defense
• Evans Gambit
• Philidor Defense
• Petrov's Defense
• English Opening
• Vienna Game

What is the point of these obscure chess moves?

The February 2018 issue of Chess lists the top twenty openings compiled from a list of 5449 December games where both players were rated over 2400 Elo. One can not take position on this list too seriously because it is greatly influenced by how the openings are grouped. For example, all the Retis are grouped together, while English is separated into 1...c5, 1...e5, etc. Nevertheless, for what it is worth, some of the list entries are: 418 Retis, 201 King's Indians, 192 Caro-Kanns, 176 Slavs, 176 declined Queen's Gambits, 143 Nimzo-Indians, 140 Kan Sicilians, 136 1...e5 Englishes, 134 Najdorf Sicilians, 127 1...Nf6 Englishes, 117 Taimanov Sicilians, 108 Berlin Lopezes, 103 Queen's Indians, 96 1...c5 Englishes, 93 Giuoco Pianos, and 91 Pirc Defences.
"... A typical way of choosing an opening repertoire is to copy the openings used by a player one admires. ... However, what is good at world-championship level is not always the best choice at lower levels of play, and it is often a good idea to choose a 'model' who is nearer your own playing strength. ..." - FM Steve Giddins (2008)
