"And another concern: if people don't earn money themselves, the tendency is to waste, in all regards."
I have not observed the same.
My impression is that the trend is we, people, like to waste when we don't have to pay, but if the money come from our accounts, we start to get careful, independently how the money arrived to our account. People would not like to waste their money even it's from a basic income.
The motive for wasting is that the money-giver might want to see your bank account balance before giving. Not having savings is generally a requirement for receiving welfare after unemployment benefits have run out. It's something basic income would do away with.
