I agree with you in principle. Wasting energy like what this and hashcash do is unfortunate but that's what happens when you have an irrational hate towards a technology rather than how it is used.
That said, modeling it after a general cryptocurrency is probably a bad idea since it rising prices may prevent legitimate clients from being able to connect to onion services due to the challenge being too expensive (either in terms of computation or accusation). I think a much practical approach is to have each visitor contribute to a partial solution that can then be combined to derive funds (much like how mining pools work). That way, clients will be completely isolated from cryptocurrency and sites can actually benefit from the work rather than just throwing it away. It's a win-win situation.
I hope the next generation learns from our senseless technology-burnings.
>modeling it after a general cryptocurrency is probably a bad idea
Not modelling after but integrating of an existing one. Because this saves massive amount of engineering effort.
>rising prices may prevent legitimate clients from being able to connect to onion services due to the challenge being too expensive
Obviously, the price for legitimate clients would be much cheaper, as their requests shall be placed in the middle of priority queue (clients can wait a few seconds) while the attacker have to occupy the very top of this queue all the time. Also note that the bigger the DDoS in this scheme - the bigger profits server could make, which he could spend on expanding capacity.
>each visitor contribute to a partial solution that can then be combined to derive funds
This scheme predates monero, which was about 10 years ago.

Not if they would reinvent the wheel each time instead of adapting of existing tech to current needs.
