I certainly don't think multiple tees in golf and architecture should be considered "lazy architecture".
If one looks very carefully at the evolution of golf and architecture in about the last 120 years one can see that increased tees and teeing areas and increasingly varied distances from which golfers of vastly differing physical abilities may start any hole is essentially golf's slow and evolutionary attempt at political correctness---eg to treat everyone and anyone as equally as possible!
Over that time the idea and basic goal is that theoretically anyway everyone no matter their vastly differing physical abilities could (theoretically) arrive at the green in the same number of strokes (and astoundingly even using the same types of clubs to do so!).
The idea of GIR, which is relatively recent and is becoming an inceasing fixation with all is the result of all this increasing fixation with political correctness or equality for all!
The ever increasing use of multiple tees is nothing more really than an attempt to better perfect handicapping in golf, and it's been that way for about 80-90 years and is definitely increasing.
If one really looks closely at the ever increasing use of multiple tees in golf over its entire evolution it's probably not much more than golf's attempt to condense down nearly everyone to the point where no one basically would need to receive more than one stroke per hole handicap-wise from anyone else and certainly never more than two!
In golf, there's only two ways to handicap really---give golfers who need it the appropriate headstart in distance and a stroke if they need that too! Why do it that way instead of from the same tee for all? Probably simply because it's just easier to do in a mathematical sense---and handicapping in the end is all about math since golf is always broken down into stroke increments for all!
Ron Prichard had a fascinating remark in his Aronimink master plan from Donald Ross in the real old days when he mentioned that once everyone played from the same tee markers on all holes---and if it took the strong man two shots to reach a green with his best and a lady four shots to reach a green with her best that's just the way it was.
But that's too difficult to constantly calculate handicap-wise so golf began to evolve into giving those that physically needed it an appropriate headstart distance-wise too so as to try to keep handicap stroke allocations as close to a single stroke per hole as possible.
In my opinion, multiple tees is nothing much more than golf's attempt to handicap as easily as possible. That's were it all started and it hasn't changed except to increase the adjustment as equitably as possible.
And in my opinion, to start everyone from the same tee markers again, as golf once was, would be massively more difficult to do architecturally--given this modern day expectation of equality or political correctness for all. I don't think that means that architects who build multiple tees are lazy architects they're simply responding to expectation today which is apparently a necessity of how golfers' today basically feel about the entire concept of handicapping which is everyone should be made to feel as equal as golf and architecture can make them!
Personally, I think I'm sorry to see it all come to this----which I guess means I agree with Jeremy Glenn---at least on some golf courses.
The little old man does not run the 100 yard dash as fast as the world champion sprinter (does not get to the finish line at the same time) so why make him feel like he could or he should? Obviously the reason one makes him feel more like he could or should (giving him a headstart to get to the finishline at the same time) is because it just makes him feel better--he doesn't have to think about his inadaquacies as much as if he had to start from the same point!
If some little old guy starts a hole 150 yards closer to the green than does Tiger Woods and he makes a four and beats Tiger on the hole with his handicap stroke what does he remember most---the fact that he beat Tiger on that hole or the fact that he started the hole 150 yards closer to it?
The answer is obvious and that's why we have more and more multiple tees in golf, in my opinion.
