First of all, it is not the likes and needs of buddhas and bodhisattvas. Buddha and Bodhisattva put down their persistence and did not covet everything. This is what people in the world like, feeling luxurious, imposing and dignified. Therefore, buddhas and bodhisattvas all use the convenient method to decorate the Buddha statue with gold and silver jewelry, so that people in the world will feel happy and respectful when they see the Buddha statue. The essence of Buddhism is education to make life perfect. These jewels are like teaching AIDS used in the teaching process.
Buddhas and Bodhisattvas do not need people in the world to provide treasures, but they are of great benefit to all beings. Buddhas and bodhisattvas have good things to give to the world, but you have to create opportunities yourself, so the Buddha advised us to provide three treasures.
The Buddha also taught us that if we see through gold, silver and jewels, we should not be obsessed with them. Buddhists and Bodhisattvas advise us to give alms and use treasures and money to help all beings and accumulate blessings.
