Iron, lapis, gold, diamond, and emerald blocks do not drop when broken with a gold pickaxe

Works correctly. Gold pickaxe is equal to wooden pickaxe and ores will not drop when mined with them. You need iron, diamond or netherite pickaxe to mine them.

It even don't mine Coal

It doesn't make sense to gold and wood pickaxe be the same

Then whats the point of it .its even a teaser in the minecraft nether update that can be really pointless
