They can, but only as long as they don't care about money. But musicians also need to pay rent.

You can't put Rammstein in the same league as my friend who would like to make a living in music but realizes that it's unlikely he'll ever make pay-the-rent kind of money from that, simply due to the sheer volume of competition and luck involved (while their music is as good as any song I've heard in the genre, it's a combination of reaching the right people and stumbling upon better ideas than your competition, which both have a significant luck factor). The former can do what they want and still get that private jet, the latter has to "spend their time riding a perpetual wave that they have to continually feed" and likely still couldn't pay the rent. That spectrum is way too broad to generalize into "musicians".
I'm not even that big a fan of Rammstein, just a few of their songs I like :)
And that was 2012 - I'm sure things haven't improved since then.
