My idea to remove Too expensive (not entirely)

Everyone hate the "too expensive", but I think is not that bad. See, if in real life you have a knife, if it breaks you can buy another one, but let's say it has sentimental value, so you sharpen it, and repair it, sharpen it, and repair it; That make no sense! the "too expensive" basically means "is cheaper craft/buy another one, you know?" and that's not bad, the bad thing about the "too expensive" is that enchanting process is annoying. I think this is because the balance, and do the player not being able to have too many enchantments, but still being able to have all enchantments! There are my ideas to improve the Anvil and make it less annoying to use:

1- Do the message appears only when you fix too many times your tool/armor

2- Now the player can have every enchantment he/she want, except, of course, incompatible enchantments

3- The player now doesn't need to add enchants in a specific order to save xp, because every enchantment cost the same...

4- ...The only case where the enchantment is more expensive to add is when the enchantment is incompatible, you can still be adding it but is expensive

5- Finally, we need to find a balance to the adding cost, considering the player can make xp farms but having empathy with those who don't want or don't know how to do this

Thanks for reading! I hope this post can help to improve Minecraft experience :D
