IMO you spend more money doing preventive maintenance. But if being finicky and tinkering with your bike is more fun or adds to the fun of your cycling, then go for it. I'd rather be riding than fixing though.
There was a time that I use to completely disassemble, clean, lube, reassemble and adjust every part of my bikes monthly. Seems that at that time I was a little more than 100 pounds dripping wet. I also waxed my car weekly. The 70's are long gone for me.
I too have only had issues with rim tape a total of two times in over 50 years.
