Tax question on tracking transactions for tax purposes….

I can understand if you are trading Ethereum and other crypto to log and report transactions to pay tax on profits, but if you are using it for purchases or excepting it as a retailer, do you really have to track every single transactions price when received and used for purchases and then trace it back to when you acquired it so you can report on the profit/loss on each ethereum?
Sounds extremely tedious and very time consuming.
