Although I absolutely think we've gone overboard on tipping, I genuinely think tipping shouldn't be completely banned. Rather, ban expected tipping.
For instance, last time my wife and I were in London, we, as a clueless American couple, visited a tavern during their busiest period after work. We left a few pounds above and beyond the bill because it was clear they went above and beyond to serve us promptly and excellently despite the fact that they were literally overflowing with patrons. That's how tipping should work.
President Unelect Musk is doing fine with that all on his own.
