The issue isn't so much about water usage, but water pollution. Golf courses don't usually make the tap water undrinkable.

Also, the "pollution" from data centers is just "major construction project temporarily disrupts water table" not "facility is pumping random chemicals into the water".
That is to say, nothing about next door neighbors to a major construction project getting mud out of their well for a little while is unique to datacenters.
I did not say that golf courses are pollution free, but there is many degrees of magnitude difference between the mere possibility of illnesses becoming more common around golf courses and data centres that have to pay millions in fines as they are not following the rules.
I feel like you're constructing straw men arguments here despite the very obvious polluting behaviour of datacentres.
