Mandating and accepting broad use of text watermarking at scale seems prime to enable all sorts of dumb and chaotic downstream effects. Not only do you start to pollute further corpus at scale - hijack text space bandwidth and fidelity - but you open the societal door to gradually add additional pieces of information - such as author identities or ad tracking information - which can then not just directly reveal a single author, but potentially larger graphs of information propagation without it being clear to anyone propagating such a trace.
