i agree with the OP and dont like it. shoes have more than germs, they have lead which can't be disinfected away...but thats maybe looking too much into it (which i do), sand/rocks/gravel get in shoes and can ruin surfaces...and socked feet are very slippery..
i am very hands off also, but not to the extent where peoples things cant be damaged...things are just things but things dont last if they arent taken care of, thus avoiding having to buy more things to replace the now discarded things that were damaged prematurely by doing stuff like this
and i dont think it has foresight....most kitchens are playwood and/or tile and the stuff my kid could climb on in other rooms or outside is different than a kitchen, entryway, or bathroom...and i explain that to them. my kids are also good climbers and steady on their feet, but in moments of stress or fatigue they make poor judgements and slip or fall easier...i have to help them and protect them and teach them when they can let loose and when to show caution.
some may be comfortable with it, and thats cool....but its okay to not be comfortable with it, too. i really dont think this falls into the 'overly uptight' category, either. i am very laid back imo, and it just seems rude. i also dont let my kids jump on someone elses furniture...just as i dont jump on thier furniture, either. my kids like to jump, so i take the cushions off and let them jump on those seperately. my last sofa was cracked (the frame) by my nieces jumping on it, and i had to use a wood splintered/dangerous sofa for a long time because i could not replace it....and then when i could replace it, it was upsetting that this sofa would now be in a landfill when it didnt need to be.
the only people who dance on tables in my family are the adults
